A word for the unexpected reaction of laughing in a situation of complete hopelessness or laughing with sad undertones.
Gallows humor is 'humor that treats serious, frightening, or painful subject matter in a light or satirical way.' It has the connotation of someone laughing at their own execution. Urban Dictionary actually has a good summary: gallows humor Sense of humor that arises from stressful, traumatic or life-threatening situations where death seems to be an inevitability. Different from black humor in that comments of this sort are made by the person/persons affected (i.e. about to die). It is not always used to mean that the person is facing literal death, but the idea is the same. They are expressing amusement or using humor in the face of their own inevitable fate.

Possible Duplicate: Capitalization for a bullet list Let's say I have a bullet point list e.g: Point 1. Point 2. Point 3. Notice I have put a capital letter for the starting letter of every bullet point and a full stop at the end. Is this the correct way to do it? If not, what is the correct way to do it? Do I put a capital letter and no full stop, or, the other way around, a full stop and no capital letter? Alternatively, do I not put a capital letter or a full stop? Is it only necessary to put a capital letter on the first bullet point and full stop on the last bullet point? For reference, I'm from the UK so British-English grammar would apply.
I found a site quoting the Chicago Manual of Style. I don't have the style manual handy, but this advice mirrors what I know from my personal experience. 'A vertical list is best introduced by a complete grammatical sentence, followed by a colon. Items carry no closing punctuation unless they consist of complete sentences. If the items are numbered, a period follows the numeral and each item begins with a capital letter. To avoid long, skinny lists, short items may be arranged in two or more columns. If items run over a line, the second and subsequent lines are usually indented.' CMOS (6.127-28) So if you're just listing points you would do: point 1 point 2 point 3 (it is only necessary to capitalize points if they are 'longer phrases' or follow a numbered list.) If you were describing them, it might be: This is something about point 1. This is something about point 2. This is something about point 3. Edit: Adding this to answer Ryan's question in the comment. Here is an example of combining both the enumeration of the items and the description, using one of the examples from the site I linked: A computer lab needs various equipment: Computers - Obviously a key component of a computer lab. Desks - You need somewhere to put the computers. Chairs - People need someplace to sit. etc.

Which one should I prefer? Is it worth it? or Does it worth it? 'Is it worth it?' is correct. Additionally, is the following form (without it) correct? Is it worth? No, that's wrong, worth always needs another word, like 'worth twenty pounds' or something.
