Nope, there really isn't any question about it for me. The more I share, the better I feel. About the only thing I find it hard to share is lampwork. I really, really have to love someone and trust them before I will let them have a lampwork bead from my vast collection; I do not easily share my lampwork beads.
In fact, I'm Gollum-like in my lampwork hoarding; I'm not above caressing them and murmuring, "My preciousssss..."
But really, that's my main selfish spot. I'll hand over just about anything else.
