For the most part, I do like to know that my stuff is going to someone who needs it or can use it. But, to be100% honest, if I found something I gave someone in a yard sale or for sale at a flea market I wouldn't let it bother me. My main goal is to get it out of my way. That being said though, if someone wrote and said "I would like your item but I will re-sell it." I would more than likely give it to them because above all else, I appreciate honesty.
I too have had people get angry because I offer an item to someone else. Hey, it's MINE, I will give it to whomever I choose, not the first one that responds! I have had a few nightmares with freecycle though, I offered a beautiful dresser...I just didn't have room for it. A lady wrote and told me that she could use it because her old one was all too pieces. I offered it to her and when I started asking about when she could pick it up, she asked me to deliver it.....I told her than I couldn't because I didn't have access to a truck. This woman had the nerve to tell me that if I didn't have a truck then I should be willing to rent a U-Haul and bring it to her!!!! I went off the deep end on that one and even though it made me furious I still replied kindly that I wasn't in a position to do that. Then, I got a really NASTY email telling me what a horrible person I was! The next day, she wrote again and told me she was able to get a truck and would be here in several hours to pick it up. OK..this time I did get a little ugly. I told her that after her NASTY email from the day before that I would burn the %$#& thing first!
