OK proper rant today...
I know different people have some very different ideas on "borrowing" stuff.
Some people have very strong views on property ownership, and would not dream of touching something that belonged to someone else and would expect the same for things they have.
Some people have a much more relaxed view, and feel that they could just use something that belongs to someone else if they thing what they are doing is no harm. Some people would assume they can just take stuff even if it is a consumable such as "borrowing some coffee, or milk, etc"...
I can see there are different views on this, and I an not trying to be totally anal, honest.
Of course, it makes a difference what relationship you have, and with a family in a household it is normal to borrow stuff from other people, usually asking or at least informing them. It is also usual, I think, to take in to account if people do have strong views they have made clear previously.
There are lines that get crossed! I don't mind too much my kids borrowing stuff if it does not effect me, and ideally if they ask.
What really pisses me off is borrowing stuff, not asking, not telling me, not putting it back, still not putting it back when I came to use it and got cross, still not putting it back a day later, and a day after that and a day after that, and then finally trying to fob me off with something else and losing what they borrowed!!!
You know who you are - it is not acceptable.
If I want to use something that is mine, I expect it to be where I left it and in the same state I left it (e.g. not battery suddenly flat, etc). If you can borrow it without affecting that logic, then that is generally OK, but not otherwise.
PUT IT BACK!!!
