I have a market stall as a hobby, selling kitchen and personal accessories that I make. Today some friends came to the market and we were chatting, when I noticed that she had picked up one of my lavender sachets. OK, fine, I went on chatting with her husband, and assumed she would either ask to buy it (only 3 euros) or put it back. But to my surprise she just walked off with it as I was talking to someone else. We have all done similar things and I thought that as soon as she realised she had taken it by mistake it she would come back, but she didn't. Later they walked back past my stall and she had nothing in her hands so she must have put it in her bag. They waved goodbye as they went. What do I do? They are quite good friends and her husband has helped me a lot in the house and garden with odd jobs I cannot do myself. I don't think I can bring myself to challenge her, but what if she is as embarrassed as I would be? Maybe she did not realise she was still carrying it when she left and then didn't know what to do? Maybe she thinks I didn't notice? Any ideas? Maybe I should give her a gift pack of sachets for Christmas!!
