What are good questions to ask to see if your friends really know you?

Do they know your middle name?

Do they know your phone number?

Do they know your favorite color?

Do they know who your crush is?

Do they know your favorite singer?

Do they know your favorite T.V. show?

Do they know your favorite food?

Do they know what pets you have?

Do they know what color underwear you wore on the third Tuesday of last month?

...Just kidding
