Grandpa, Aunt Kelly, and Cousin Patrick, along with Emily and Callahan came over as well.
He also has these fun little things they called "dolphins" that propelled them across the pool. They were easy enough to use that even Irene had no trouble with it.
We had a great time meeting Bob. The kids, in that way kids have, quickly labelled him "Uncle B" since he and Aunt B are together. :)
