My son just told me that it's Solstice. You're supposed to be able to take an egg and stand it on its end - or you can walk around the park naked wearing a pair of horns. He tried the egg bit but it didn't work so I threw a dishcloth on the counter and then it worked. That's what fathers are for. I didn't want him running around the park. In the long run it didn't matter, he doesn't have a set of horns.
