Is it normal that i don't really care about my extended family?
So, this is my situation. Tomorrow is my grandfather's birthday, and my family is visiting them. I'm expected to go with them, but I really don't want to. Mainly because I don't really care for them, but also because its like an 8 hour round trip. My parents acted like I am selfish and rude for not wanting to go. I mean it's always that way, even with other members of my family, my aunts and uncles etc. I just don't care about them.
So I guess what I'm asking is, is it normal to not care about my extended family?
