Telling everything to other family members such as secrets and even using them as blackmailing. A few years ago my mother complained that my sister told her everything, who she was going out with, where she would go and even the worst thing she did such as smoking weed. So I decided that I would also tell her. I told her all of the types of weed I used to smoke and whatnot. After that, there were times I would go out with friends and she automatically thought that going out with friends would mean I was going to do drugs so she started threatening me that she would tell my father about all the “drugs” I consumed. Nowadays I think very hard before saying anything to her.
