Would this annoy me? Well, no! If you were away for the day and your Mum needed the car, why should she not have used it, as long as she is legally allowed to??? So, you have never borrowed anything from her? Have you always returned what you borrowed in perfect condition? Was she out shopping for the family ... including you etc.??? She is your Mum for heaven's sake!! Although it would have been nice if she had been able to tell you she needed to borrow your car, I am sure she has done far more for you than you have ever done for her, so I think you should not play the tough nut here. As for the top and jumper, which she probably has the honour of washing every time you wear it ... I wouldn't be the least bothered if my Mum borrowed clothes of mine for the day. My daughter occasionally borrows things of mine and I am fine with that. If I want to borrow anything from her she never minds either, but then we really are very close. You are talking about your MUM, your CLOSEST FAMILY, remember???!!! If you are going to kick off about giving your Mum a bit of liberty, then I feel sorry for you. You make yourself sound like a very possessive young lady who thinks her Mum owes her ... Might it not be that in truth it is the other way round??? Come on, be nice. :o)
