I know I'm totally reviving an old thread but what ever happened with this? Did the OP get the hook back, forget about it, have a good old fashioned smack down in the parking lot of Denny's? :boxing:
What a terribly rude acquaintance. I bet she has done this before and gets away with it, banking on the fact that considerate people prefer to avoid such awkward discussion. I've learned over the years that awkward discussions are not awkward for me...they are awkward for those who exploit the goodwill of others, including mine. This is exactly why they do it, because it works, and because they get freebies out of it. Personally, I would have responded with a casual laugh: oh, don't be silly, I was loaning it to you ~ not gifting it to you, although I will tell you where you can buy your own set ~ do you have a pen and piece of paper to write it down? Here, why don't you hand it back to me while you find something to write with.
So, it actually doesn't have to be so awkward after all. She caught you off guard, which is what (I believe) she wanted to do.
As a quick aside, when I was younger and more naive, I had friends and acquaintances who pulled such crap...and I put up with it thinking this is what we tolerate with friends. I learned that I don't have to tolerate anyone who helps themselves to MY things...they are mine, after all. My friends respect MY things and ask to borrow them. If I say no for whatever reason, my friends respect my decision and leave it at that. If they can't, they're not worthy of my friendship, simply put. Lay down the boundaries or others will violate them because it's no skin off their nose. Today a purse hook, tomorrow, who knows, kwim?
