J.D.
Don't be bummed. I've been to the parties where as few as 3 people have shown up. I think the most amt of people at one was 10. I don't go sometimes because I am not interested in what is being sold or just can't afford it.
You should have food and drinks. Finger Foods would be just fine. I wouldn't over do it on the food though. I would say that Cheeseball and Veggie Tray would be fine or Maybe a cheese tray with pepperonis and Veggie tray.
