Ok, so I don't personally think this was a big deal but that might be because I don't drive and my partner has an older car just to ferry the kids around. Interested to hear other people's thoughts nonetheless.
I made plans with a close friend last night to stay over at her house and have a night in. I went for a walk along the beach/dip in the sea beforehand and she picked me up afterwards as it was only down the road from where she lives. I jumped in the car and without thinking, I put my blanket/towel/bag on the back seats of the car. It's not a new car but it's new to her as she bought it around 3 weeks ago I think. It is quite an expensive car and has clearly been well looked after so I felt awful, as all my belongings were covered in sand. I hadn't realised what I'd done until I pulled everything out and the seats/floor were covered in the stuff.
I did apologise and offered to clean up but she said it was fine, although it clearly wasn't as when I came out of the shower she was outside cleaning the car. This was at 10pm. I told her I would have done it but she said no and told me she wouldn't be long. She must have been out there for around 20 minutes. She came in and said she'd have to take the car to be cleaned as it had all got into the seams of the seats and she couldn't get to it with a cloth. In all fairness she does live in a flat and has to park down the road so can't exactly get the hoover out. I told her I'd help her today but again she said no. She has suffered with ocd and anxiety since a young age and I noticed last night that she was extremely agitated, restless etc, presumably because of the car. She's like this with her house too.
She barely spoke a word to me last night and this morning was up walking around the house really early. I woke up around 9am and straight away she was asking me what time I wanted to be dropped off at home. I think she was rushing me to get out so she could take the car to be cleaned. Again, I apologised and offered to help clean up but she said it would need to be professionally valeted. I haven't heard from her since and it all feels very awkward. I spoke with my partner about it and he said maybe I should have offered to pay for it to be cleaned but I'm not working at the moment and I presume it would have cost around £40-£50 to be cleaned (it's quite a big car).
I understand it must have been frustrating for her and I'm usually a very clean, tidy person but it was an accident and I did apologise and offered to clean it up. Surely I don't deserve the silent treatment over this? And would you fall out with a friend over something like this?
AIBU?
