The shower...he always wants to get in it. He doesn't love it when it's actually on though. His favorite is opening and closing the door.
Playing in the fridge...if he see it open he books it as fast as he can. He loves to open the drawers, take food out, and especially take all the condiments out ...since they are right at his level.
Taking all the books out of his little library. He takes all books off the shelves until he's surrounded in his books and then sits in the middle of them and either looks at the pictures or pretends to read.
We just love this littlle guy!
