-I ended up giving the Cut Direct to a guy I've talked about on here before. He was a pathological liar and a narcissist (and I suspect actually diagnosed, as he had talked about his parents making him go to therapy before) and I told my parents that I wasn't going to talk to him anymore. They and my brother said I should still be "nice" to him and that it would be rude not to attend a gathering of mutual friends
just because this guy wasn't going to be there. In order for them to see things my way, I had to list off: the fact that he said "Adelaide, your parents
love me. They think I'm awesome", and the fact that he started snickering when I told him our dog died. At the last one my brother wanted to fight him, but I managed to talk him down.
-My ex-friend from high school was and is da
ting a guy who has been rude to my face before. I have told her several times that I didn't want to ever see him and couldn't stand him, but if she could then that was fine as long as I didn't have to deal with him. One day she drove down from her college (a few hours away from my house) and pulled into my driveway unannounced with this guy in tow. I wasn't there, thankfully. She stood in the driveway with her horrible boyfriend for about 30 minutes talking to my parents and then called me "rude" because I didn't want to see him.
-ETA: The same ex friend had a habit of commenting on what I was wearing whenever we went somewhere. For instance, a group of teenagers would go to a decent restaurant and afterward would walk around town. For an outing like this, I'd wear a sundress, heels, and some makeup. Nothing overdone, but not jeans and a t-shirt either. I was always relatively dress-code conscious and almost none of my friends (save one guy) were. Ex friend liked to comment on what I was wearing to the point of making people uncomfortable. I only see now that she was trying to make
me feel rude for dressing appropriately for where we were going, while she was usually wearing something off-the-wall that was far too casual.
-I have told my parents that I am studying something of a sensitive/polarizing topic in addition to law school and I
do not want anyone from back home to know what it is for various reasons. I have told my parents what to tell people when they ask. We have been over it. One day I came home and my mother casually said "Oh yes, Mrs. Smith wanted to know what you were studying and where you wanted to work, so I told her [exactly what I'm doing]." I asked her why she would do that when we had been OVER what she should say, and my mother snapped back that she had forgotten and it would have been rude not to tell Mrs. Smith
something. She continued by saying "I'm not going to lie for you" and insisted that it would be "rude" to lie or fudge the truth to random people who wanted to know. I now tell her that my dream in life is to study international law and work for Coca-Cola.

(My brother, who's in the Marines, was literally speechless at this exchange.)
