In Illustration class we had to illustrate the "do's and don'ts" of Valentine's Day. They were basically rules to go by so that you and your partner could enjoy the holiday to its fullest. I was assigned to draw illustrations that were geared towards men.
My "don't" was: Don't do guy stuff.See, you idiot?! She doesn't like that!
My "do" was: Do make her a homemade valentine.What a nice young man.
