Halloween costume party turned into birthday party

One of my clients invited me to a superhero themed Halloween costume party. Recently I got a phone call that too many people are coming and several cannot attend anymore including myself due to parking and space problems for that apartment building.

Today I was told about a superhero themed birthday near my home that I could possibly attend. Hopefully that will actually happen. The person who said I could come mentioned that it would be funny if I show up in a female costume. Based on what is left of all the people renting from me, I might end up having to do that.
