It's a cleansing process, and she knows it went to the best possible place. A lady at church went through a spell last fall. Her friends were dying off (3 in one month!) and she was feeling her mortality, so started cleaning out her house and asked my help. I got a couple of totes of usables. The rest was leftover laces and such from making bridal gowns, maids dresses, costumes, etc. that she donated to different places.
She got over it, and now we spend a couple evenings a month rebuilding her stash :) She's much more intentional in her purchases now, but she's having fun, and I love watching her have fun.
