Acting all nice with visitors and then saying how awful they are as soon as they leave.

Not being included in any decisions/no autonomy. Although I did realise a bit as a kid, when I was with a friend and their parents were asking them questions, like what they wanted to do on school holidays, and actually including them in their plans, and I was absolutely floored. What, you don't just have to tag along with whatever your parents to and try and make the best of it? They actually do things FOR you and with you, like go to movies and theme parks and stuff???

Also, being physically provided for but emotionally neglected in general.
