In this style, you write a phone number vertically, with each number beginning the poem's line. Then, each line of your poem must include the same amount of words. For example, 4 would include 4 words, 7 would have 7 words, and so on, all displayed vertically as in an acrostic poem. When someone calls your number, they will be directed by your service provider to your favorite food store, movie theater, or any other place that sells words. People love phone numbers because they are easy to remember and they can contain many characters. There are only 10 digits in a phone number, which allows for a lot of space for creativity. Phone numbers were first used to identify telephone operators who would connect callers with people or services, but now they are also often included in electronic messages and advertisements. Phone numbers were originally printed on paper bills but now appear in many other forms including online. Phone numbers were invented in the 1800s and have changed very little since then. They are still made up of alphabet letters and decimal numbers with no spaces between them. A single number can represent multiple voices or lines at a time if they use different phone companies or cell phones. People often think of songs as being used to describe emotions but actually poems are much more effective at doing this. Poems can make anyone laugh or cry, even if they don't know you.
