I'm not even an introvert and this happens all the time. If I just got back from a long exciting trip and someone asks "How was your trip?" I've learned that nearly everyone wants the single sentence answer, not the actual info about any of the exciting things that happened. It's as if people need to acknowledge that they know you were on a trip, but don't want the answer to the question they asked.
@xlaxxine Hey. I haven't seen your username here before. Are you new here? :)
P.s: that sounded a lil bit sarcastic ^^'
