I sold a doll to someone quite cheaply because I needed the funds. When the buyer received the doll, she seemed happy about it and said the doll looked awesome. After a month, she listed the same doll for $200 more than what I sold to her. I'm not upset about that because it's now her doll. But I get a sense of guilt for selling to her a doll that she maybe couldn't bond with. I don't know.
