Your parents often ask you to turn down your music
Their Clothes are weirdly out of style
Some times you'll come out into a room and catch them quietly just sitting there perhaps reading a book
They enjoy eating at least one of the following:eggplantanchoviesoystersorange marmalade
During the winter they keep the house uncomfortably cool.(bonus points: Whe you complain do they tell you to put on a swetter?)
They completely over react when your room is the tiniest bit messy!
On more than one occasion they have been embarrassed to be seen in public with them.
They tell jokes that regular humans do not find funny.
