We passed on a birthday party for the girls this year. Instead we did some special things. The Lee kids came home with us from the science museum to play for the day.
I took Ally to get her hair cut (a treat for my kids) in the afternoon. And let me just mention here that the salon would let you pay with a debit/credit card but you could only tip with cash or check! Weird. And a really bad policy. I was a little embarrassed to tip with $4 worth of quarters! But not as much as I would have been if we walked out of there without tipping.
