And I like to oblige if it's within my gift.
I don't ask them for money or intricate details of their lives,I say 'yes'-'of course you can borrow my car,I won't need it back until Tuesday'.
I hand over the key and watch my car drive off with my happy friend inside.
Isn't that nice? - yes I think so too.
So when they bring it back on Tuesday and there is no feckin' petrol in it and I have to coast up to traffic lights in an effort to the to the petrol station? - or worse still, although in this case I don't have to rely on the fumes to get me there, people who have borrowed my car put some petrol in and I know they not only clocked where the fuel gauge pointer was as they trundled off down the drive with my car, but have done the calculations as to how much in litres and money terms they will have to put in the tank to return the gauge to the precise location it was reading when they started it up 4 days ago.
They must have it imprinted on a mental image in their heads that they referred to 4 days later, so they could drive up to my house looking all noble because they haven't written it off or got any tickets,they are all pleased with themselves as they announce, handing the key back - 'I filled it up!.
No, no you didn't really, did you?
Tell 'em there's something wrong with the car, to avoid offence. They'll work it out.
