I sold a machine to a neighbor's friend really below what it was worth. She sewed on it for about an hour, loved it but then every time she had a problem about sewing, not the machine, she called me. Every time she had a question she called me instead of reading the manual. When I stopped taking her calls my neighbor said her friend was having a hard time trying to figure out how to sew without any help. I told her I'd buy the machine back as I was tired of her constant helplessness. I would sell a machine to a stranger before selling it to someone that knew me or of me.
