train sets are exciting

isaiah was enjoying his train set today. his main interest lies in the bridge and in shoving the cars under it. that's pretty much all he does. he's been doing this laugh lately - where he sticks out his tongue and says hhhuh! hhhahh! i was trying to capture it... when i had the flash on at the beginning after about the third picture i got this look from him - "are you seriously going to keep flashing that thing at me??!"
