Don’t live in the same apartment with your mother after the age of thirty. It’s sort of weird.
Don’t accidentally call you mother your wife’s name during dinner. It’s a bit odd.
Don’t go with your mother to a Jewish Deli and think it would be “fun” to sit at the same table where Sally had her fake orgasm. It can be embarrassing.
Don’t assume your mother is sleeping in her bedroom during your imaginary passionate tryst with a hostess from the Food Network in your living room. Don’t ask.
