I'm hoping those of you who have (now) been to a swap can comment on this.

I'm finding myself, as I assemble my growing swap pile, feeling sheepish about adding some items to the pile, for fear of having to answer the "But WHY aren't you keeping THIS?" question. Silly, I know. My only criterion for adding things to the swap pile is "I find myself not wearing it," but then I feel that I'm not shopping wisely if I'm buying things that I don't wear.

So my question is, is "But WHY" a question that actually comes up at a swap, or are people just happy to see something they like and not so interested in why you're swapping it?
