Little Drummer Boy's comment on the D&D thread made me think about this:
When I became one of the borg, I threw out about $600 worth of pnp materials and books, a fact that I was proud of at the time and which makes me sick now because almost all of it is irreplaceable
He also threw away who knows how many CDs that were "bad" for dubs; also threw away a framed picture of a dragon that was really cool, and maybe some cool rock band t-shirts.
I don't remember having to physically throw away a lot of stuff, but I had to resign from the citizen's band I was in (played the clarinet), threw away my good friends from high school, etc.
What did you all throw away when you became dubs that you regret now?
