Recently, my the house next door to my grandpa's house burned down resulting in part of my grandpa's house getting burned. The damage isn't too bad, but bad enough that the house can't be lived in. My dad lives across the street and owns the house next door that my neighbors and grandpa are currently staying in. I live down the street.

I helped them prepare the house next door for others to stay in, but haven't helped with anything else since. They are working on clearing out the house so it can be repaired and I have refused to help with it. My dad is now mad at me because I refuse to help. He comes over in the middle of the day (I work nights) and asks for my help to which I refuse because sleep, and even on my days off, I tell him I don't want to help.

For a bit of context, our relationship is very rocky as I hold a lot of resentment from him from my child hood between all the anger issues and the borderline abuse, as well as the amount of time spent working and basically not having a childhood. I still only deal with him because I live with my brother and he interacts with him semi-regularly.

He had just come to ask for help with moving something from the garage so my grandpa can put his bike in it, I told him no and he said "Fine I guess we will do all the work ourselves. Even though \[grandpa's\] house burned down." and stormed off.

TL;DR AITA for not helping my dad, that I already don't like that much, when my grandpa's house burned down?
