aita for not celebrating fathers'/mothers' day?

I don't generally celebrate fathers' day or mothers' day. I don't even know when the dates are. The last time I really knew about it was when I was in primary school and they'd have us make a card. I have a very small family. I live with my parents and my grandparents live a couple of hours away. Sometimes we celebrate things together all 5 of us, or go out for a meal maybe but I don't go out of my way myself to do anything.
I don't really have that much chance to get out of the house and get a card. I leave the house for college but I don't just go into town for errands and such.
I don't have a close relationship with my parents. It's not a bad relationship, they're nice to me but they don't really know much about me. They haven't bothered to ask or made any effort to show that they'd care so I haven’t really felt like I’ve had the chance to talk to them about the things I like. I have little to none emotional bond with them. I care about them as people, I love them because they’re my parents and they’ve given me a nice life but I don’t have an emotional connection with them. I can’t speak to them about my mental health because my mum gets angry and my dad gets condescending. I don’t talk to them about anything. I don’t want to talk to them about anything.
I'm not really looking for any replies or advice or anything, this is just a vent to get things off my chest.
