(I own too many books. My wife wants me to screamline my books (YET again!!) and fucking give some MORE away, FFS!)
I could never agree to that sort of thing. Never.
I get to choose who and which ones. I have given many books away to special people, but just the right book, if I can.
I donated a few hundred (sixteen good sized boxes) to the local library (I died a bit) when we sold our big house and moved into this one. She laughs at me when I go there and check one of them out to re-read.
I hear you, but I have given away more books than I can count for the following reasons:
A) No space
B) I'll never read them again.
C) Lost interest in the subject
D) I have read it so many times that I have the plot memorized.
E) I am so tired of carting them around from place to place to place
F) It frees up more space to buy more books! THAT IS THE PRIMARY REASON!
