This paragraph demonstrates the importance of punctuation. All of the words are exactly the same and in the exact same order, but the meaning changes entirely with different punctuation.
Dear John,
I want a man who knows what love is all about. You are generous, thoughtful, and kind. People who are not like you admit to being useless and inferior. You have ruined me for other men. I yearn for you. I have no feelings whatsoever when we're apart. I can be forever happy - will you let me be yours?
Gloria.
