I feel like I've done the wrong thing, but not sure why. I borrowed a small garden tool from an acquaintance who said to keep the item as they would be able to get another. Well, silly me, returned the item, saying thanks very much for the loan but didn't want them to be left without, so I'm returning it. This happened within the space of a few hours. This was met with a rude, kind of haughty response. I don't know what I did wrong. I thought I was being nice by not putting the other person out.
Would anyone be offended if someone gave you back something that you'd told them to keep?
