A thought has occurred to me (scary concept, I must be ill). I'm going to two events over the weekend where people need to bring their own food, etc (Fi's party and the Picnic for Peace). Since I'm only going to be there for a short time I doubt I'm going to be able to organise my own stuff for them.
So, would I be able to scrounge off some other people? I'm willing to pay for my share, no problem.
