free entertainment

why is it you can buy your kids expensive things and they would rather play with a refrigerator box for days? i think this is one of those eternal questions we will never have an answer for. after we got our new fridge, the girls couldn't wait to get to playing with the box. it was their sole source of entertainment on friday and saturday. jess' cousin trevor even spent friday night so he could get in on the fun!! i will be breaking their hearts today as the creation is going to the dump! sorry girls.
