Grammar

In grammar today we learned about Using Capital Letters. Here are some rules to using capital letters:
1. Capitalize the first word of a sentence and of each line of poetry.
2. Capitalize the first, last, and all important words in the tiles of books, poems, stories and songs.
3. Capitalize a person's title when it comes before a name.
4. Capitalize abbreviations of days and months, parts and addresses, postal codes, and titles of members of the armed forces. Also capitalize all letters in the abbreviations of provinces.

There were some rules for Using Capital Letters. Here is an example of one:

Lauren, does your friend live in vancouver, b.c , or carstairs, alberta?

Here is the right way to right it:
Lauren, does your friend live in Vancouver, B.C, or Carstairs, Alberta?
