Walter?

Walter, are you in there?

This summer I have yellow jacket wasps in the birdhouse. At first there was one. He was not aggressive.  I am not freaked out by bees so I thought, outdoor pet! I will name him Walter.  Then I noticed there was more than one. There are a few and I really don't  know how many but I know one of them is kinda grumbly. They are all named Walter. The Walters. 

My daughter thinks this is hilarious.
