My mom has been putting a single olive in every dish she makes for thirty years because my dad said he liked olives on their first date. last christmas my dad mentioned offhand that he actually hates olives and always has. he was just nervous and didn't want to seem picky. my mom set down her fork. picked up her wine. finished it. refilled it. and said "so what else don't you like." they were there for four hours. we did not eat until 9pm. my parents are fine but they're different now.
