Our DD was about 11 months old when she visited a relative's house out of state. Her next visit was at least two years later. She stared at a corner of the house, frowning, before finally asking, "Where's the tree?" This created a lot of confusion among everyone until they finally recalled that DD's previous visit had been in December. And sure enough, the corner DD indicated was where they had the Christmas tree.

I don't think she remembers the house anymore.
