WTF am I doing?

[Apparitions]

So basically my Mum just comes into my room and starts talking about how I should be nicer to my Nan (who lives with us) because she does loads of shit for me and that she thinks I don't even like her. The thing is, I don't even know what I'm doing that's so bad or whatever. It's not like she tells me any of this so I know I'm being a prick or something (I honestly have no idea what I'm doing that's so bad, seriously.) so how am I supposed to guess these things. I don't try to be mean to her or anything, her saying that I don't like her is ridiculous TBH, and I'm sat here attempting to remember when I might have come across as a bit of an asshole. I don't know, I've had exams this week and I've been very tired due to lack of sleep so maybe the stress/tiredness may have come out badly or something. The point I'm making is if my Nan feels like this then how am I supposed to know what I'm doing wrong so I can try to stop if or whatever? I' can't read her mind for fuck sake. Help, please?

Parents tend to overreact over the smallest of things, which could be triggered by them undergoing some stress, worries, etc in their life right now.

If your nan hasn't said anything to you, and yet your mum is adamant that the way you're treating her is wrong, then I think you should pull your nan aside and explain to her that your mum is accusing you of not being nice enough to her and that you would like to know if there's anything you're doing that's bothering her. By the looks of it, if you have done something to upset her, you probably haven't realised it due to how tired and stressed you've said you're feeling lately.

I guess I probably should, but I don't like the thought that my Nan doesn't think that she can talk to me if there is a problem as it just makes me wonder if I'm unapproachable and standoffish, which I hate.

As long as you're sincere and honest with you Nan you should sit down and talk with her. Preferably with your Mom out of the house.
