Jacob's raspberry fascination

Today I spotted Jacob for the 3rd time lingering around my raspberry bush with a little water bottle. I was wondering what kind of trouble he was up to and asked him what he was doing. "I'm looking at the ants mom. They used to live over here (pointing to one side of the bush) and now they moved their new house over there (the other side). I love to see how happy a child can get about a bunch of ants who are relocating (thanks to him flooding their "home" every day)!
