I hate other people holding my handbag - once when our with FIL and his partner, she insisted on holding it for me. To be fair, I was pregnant and holding my toddler so she was trying to be nice, but she wasn't holding it properly and I was uncomfortable the whole time expecting my things to fall out.
I never loan shoes. In fact I don't even like loaning my clothes. Last time I did that, a very expensive dress got returned to me missing 4 buttons and the friend didn't even say anything.
I must say, I want to be generous, but I am not well off and save to buy the best quality I can afford then take really good care of my things. As such I don't like people using anything much. Have been burned too many times. Of course that doesn't include cups and crockery etc when I have dinner parties. Just not clothes, shoes, electronics etc.
