They just chicken- scratch. It is a royal pain to read a note from a woman. Even when she's dumping you, she'll put a smiley face at the end of the note. The average number of items in the typical woman's bathroom is 437. A man would not be able to identify most of these items.

Men in a restroom will never speak a word to each other. Women love cats. Men say they love cats, but when women aren't looking, men kick cats. A woman knows all about her children. She knows about dentist appointments and soccer games and romances and best friends and favorite foods and secret fears and hopes and dreams.
