My 3 year old teenager

How did we end up with a 3 year old teenager?  I tried to evoke excitement for an upcoming, fun-filled event, to which Asher's response to, "Doesn't that sound fun?" involved a sullenly expressed, "Not really, Mom."  Followed by the eye-roll.  Okay, not a full-fledged roll, but definitely an eye-shift to the side, emphasizing how unfun it sounded.  He recently said, "Whatever." Refuses to discuss his day at school.  Retrieving information about his day is like pulling teeth.  Although, if he's really happy or excited, he'll pop.  It's like he can't contain his excitement and it comes bubbling out in the form a loudly yelled, "POP!" I love those pops.  I doubt he'll do that as a teenager.
