A toast is a ritual in which a drink is taken as an expression of honor or goodwill.
 The term may be applied to the person or thing so honored, the drink taken, or the verbal expression accompanying the drink.
 Thus, a person could be "the toast of the evening," for whom someone "proposes a toast" to congratulate and for whom a third person "toasts" in agreement.
 The ritual forms the basis of the literary and performance genre, of which Mark Twain's "To the Babies" is a well-known example.
In the United States a Foreign Service brat (also referred to as diplobrat or FSB) is a person whose parent(s) served full-time in a Foreign Service posting abroad during that person's childhood.
 The term "brat" is often thought of as derogatory; however, for some who have experienced this background, the term has a neutral feel and is sometimes taken as a sign of pride.
 A Foreign Service brat may spend the majority of their childhood outside their parents' home country.
A nerd is a person seen as overly intellectual, obsessive, or lacking social skills.
 Such a person may spend inordinate amounts of time on unpopular, little known, or non-mainstream activities, which are generally either highly technical, abstract, or relating to topics of fiction or fantasy, to the exclusion of more mainstream activities.
 Additionally, many so-called nerds are described as being shy, quirky, pedantic, and unattractive.
Kosti Vehanen (31 August 188713 March 1957) was a Finnish pianist and composer.
 As a pianist he performed in more than 3,000 concerts on four continents.
 While he did perform as a concert soloist with major symphony orchestras and performed in recitals, he is best remembered for his prolific work as an accompanist with some of the most important singers of the first half of the 20th century.
 As a composer, he produced piano pieces, arrangements of folk songs, solo songs, two ballets, and a violin and cello fantasy.
 In addition, Vehanen also penned several memoirs, including 1941 book chronicling his decade long experience serving as Marian Anderson's accompanist.
Land Arts of the American West is a studio-based field program that seeks to construct an expanded definition of land art through direct experience connecting the full range of human interventions in the landscape—from pre-contact indigenous to contemporary practice.
 Land art includes everything from constructing a road, to taking a walk, building a monument, and leaving a mark in the sand.
 The program seeks to expand upon connections between typically separate fields.
 Each fall we spend two months camping while traveling 7,000 miles to engage sites that range from the CLUI complex at Wendover, Utah to the pottery culture at Mata Ortiz, Mexico, from earth works like Robert Smithson's Spiral Jetty to archeological sites like Chaco Canyon.
 We learn from the fact that Donald Judd surrounded himself with both contemporary sculpture and Navajo rugs; that Chaco Canyon and Roden Crater function as celestial instruments; and that the Very Large Array is a scientific research center with a powerful aesthetic presence on the land.
 We spend the semester living and working in the landscape with guest scholars that expand the range of our definition in disciplines including archeology, art history, architecture, ceramics, criticism, writing, design, and studio art.
 The immersive nature of how we experience the landscape triggers an amalgamated body of inquiry where students have the opportunity of time and space to develop authority in their work through direct action and reflection.
 Land Arts hinges on the primacy of first person experience and the realization that human-land relationships are rarely singular.
Marian Anderson (February 27, 1897 – April 8, 1993) was an African-American contralto and one of the most celebrated singers of the twentieth century.
 Music critic Alan Blyth said: "Her voice was a rich, vibrant contralto of intrinsic beauty."
 Most of her singing career was spent performing in concert and recital in major music venues and with famous orchestras throughout the United States and Europe between 1925 and 1965.
 Although offered roles with many important European opera companies, Anderson declined, as she had no training in acting.
 She preferred to perform in concert and recital only.
 She did, however, perform opera arias within her concerts and recitals.
 She made many recordings that reflected her broad performance repertoire of everything from concert literature to lieder to opera to traditional American songs and spirituals. Between 1940 and 1965 the German-American pianist Franz Rupp was her permanent accompanist.
30 Days was an American reality television show on the FX cable network in the United States, created and hosted by Morgan Spurlock.
 In each episode, Spurlock, or some other person or group of people, spend 30 days immersing themselves in a particular lifestyle with which they are unfamiliar (e.g. working for minimum wage, being in prison, a Christian living as a Muslim etc.), while discussing related social issues.
 As in Spurlock's film, "Super Size Me", there are a number of rules unique to each situation which must be followed during each such experiment.
 At least one episode each season has featured Spurlock as the person spending the month in the particular lifestyle.
In behavioral geography, a mental map is a person's point-of-view perception of their area of interaction.
 Although this kind of subject matter would seem most likely to be studied by fields in the social sciences, this particular subject is most often studied by modern day geographers.
 They study it to determine subjective qualities from the public such as personal preference and practical uses of geography like driving directions.
 Mass media also have a virtually direct effect on a person's mental map of the geographical world.
 The perceived geographical dimensions of a foreign nation (relative to one's own nation) may often be heavily influenced by the amount of time and relative news coverage that the news media may spend covering news events from that foreign region.
 For instance, a person might perceive a small island to be nearly the size of a continent, merely based on the amount of news coverage that he or she is exposed to on a regular basis.
