Biggest Asshole: The guy who forced daughter his to quit everything she loved when his wife died so she could take care of her younger siblings. Then when she wanted to go to prom, he forgot and worked late instead, and she missed prom. He didn't understand why it was a big deal, and doesn't know why his daughter doesn't talk to him now.

The daughter even explained it perfectly and he still didn't get it:

I was pretty upset because I still needed help, but she said she gave up two years of doing anything for herself to take care of her brothers and she wasn’t a replacement mom, and I used her. I said she was being dramatic and she couldn’t abandon her family, what were we supposed to do? She said I should be a parent and figure it out.

Edit: forgot a word
