Being trained in behavioral psychology and watching my girlfriend's sister with her dogs is torture to me.

She's got a good boi who barks for attention. She gives him attention every fucking time. He'll be barking away in the corner while we try to talk, and instead of taking him outside or something, she calls him over to her and pets him.

I see this over and over again and think, "It's no wonder he barks so much, when she reinforces him for it constantly."

It drives me nuts and honestly makes me not want to go over to her house. I really want to say something, but I don't want to be that person coming in and giving unsolicited advice to others about how to train their pets. So I just watch it happen over and again and suffer in (bark-filled) silence.

Edit to add: Also, my brother and his kids. This one hurts more for a number of reasons. He complains about how our mom raised us, but then does the same shit with his kids, never connecting the dots. Meanwhile I learned what not to do by watching my mom. Then through education and working in the field, not only have I been vindicated for the way I interact with kids, but I learned lots of new skills that could help the kids learn appropriate behavior while maintaining their self-esteem. But when my brother's around, he's all, "I'm their parent and I'll raise them my way." Even his own parents-in-law told him, "You listen to Whats_your_reasoning, she knows what she's talking about." But no, I've got to not do the things I do every day that could help his kids and his life in the long run because he doesn't want to hear it.
