This is inspired by Remus's thread on Chat Cafe
Basically you ask if the next person has done something and then they say yes or no and explain it and then ask another Have you ever question.
For Example:
Person 1: Have you ever built a snowman?
Person 2: Yes last year and i built one with my best friend.
Have you ever rode a horse?
Person 3: No however i would like to
Have you ever played baseball?
ETC
So I will start
Have you ever had a pet
