Every year I hold an annual watch my paint dry convention. I usually charge around $50 or so a pop. I get a lot of complainers about the price and how slowly the paint drys. Heck some people even have the notion to complain about the color of paint I use!
Anyway, whenever someone mentions these minor quibbles, I just remind them that this event is bigger than the paint. It's about the camaraderie and friendships that we form while watching the paint dry.
