Am I really the jerk for bringing my nieces/nephews home late?

The kids were talking to there friend from baseball and it took them awhile to get ready to go home and they did not want to come home. Apparently I am banned from seeing them for a while because I didn't follow the rules and must be punished because I am not the parent. I tried to follow the rules. I told them we have to go several times.

My Dad is also banned and so is my girlfriend. my dad screamed at me for an hour and a half. I ended up going to a minor league baseball with my girlfriend which was fun. Sil was also mad I didn't come right away to pick them up in the first place. And almost didn't let them go. i had to do two things first.
