So far my favorite memories are:
Harrison at first running AWAY from the water and waves and eventually running into them. And it was freeze-your-ass cold.
Convincing Cooper that a "mark" that he got on his foot after he noticed a bug landing on it, was actually a serious "tinger" bite. (this after he shot me down on the bug being a "shamalang ding dong" bug). Even though it didn't hurt now, he was in danger of his foot falling off after he fell asleep tonight. The only way to remedy that was to pee on his foot exactly 2 hours after he got bit. After he asked Eric, "do you really think that's true?" he replied, "I don't know but why take that chance?", he marched into MY shower (of course) and peed on his foot. I almost peed my pants watching the whole thing.
The smell of the kids after a full day in the hot tub!
