Definitely tell Matt about the email. Let him decide how much detail he wants, but let him know that you got an email, but haven't responded yet, but likely will (because you know you will).
Barney - AGH! Run screaming. When they are little they will like the most annoying shows. Chowder, had me running down the hall to my bedroom, nothing inherently wrong with the show, just annoying. Then we moved onto the tweeny bopper shows, like Suite Life, iCarly, etc. YUCK! I do the happy dance when they decide it's time for a Dr. Who or Star Trek marathon. As they get older, they have gravitated more toward the shows I like.
