To expect people to return things they've borrowed?

Yes that is so annoying, you are not unreasonable at all. I especially hate it if books are not returned so now I only lend them to friends I can trust to return them in the same condition they got them. I never lend books to smokers. Recently I lent money to a friend who said he would work it off doing my garden, I have to keep chasing him up to do this which is demeaning to both of us.

I have had things which I have lent out and never got back and yes, it is very annoying. I would rather someone ask for me to give it to them than think that they are not giving it me back. It is a form of stealing to me. I have had family members "borrow" money and then not give it back. Just ask if I can spare some and they could have had it, for keeps.

Now I don't lend anyone anything. If anyone wants anything I would rather buy them the thing (depending on the amount, of course).
