I would always have to split the day up and not let one side of the family know if I enjoyed myself or liked my presents or tell them what had happened at the OTHER side's house. And yes, they would quiz
me and try to get me to spy so they could try to turn me against my mom, etc. Obviously, this was not fun. Soon enough, I didn't have to worry about having a good time because there was too much anxiety to enjoy myself. Over time, I became progressively more depressed and anxious each year.
