Why does everyone assume i'm cheap? It's really that I'm lazy (a much more admirable sin

.
I'm looking to have fun with my neighbors, have already said that I won't ask people to bring food -- now am looking for some helpful input about how to host a party without serving a full dinner. I don't want to deal with the dishes, don't have enough chairs for everyone, lots of picky kids involved, etc.
So no one hs ever had a party without serving dinner??
