I had a friend that started from my childhood, when I moved away from our neighborhood she and I maintained a pen pal correspondence starting when I was 6. A few years back, her politics (anti muslim actually) was the last straw for me. I called her out on the carpet, and she sicced her older brother on me, a fanatical right wing type.He actually had the nerve to play throw up on things that happened when I was 4 years old and spewed enough invective to fry a chicken!!! (what bad thing did 4 year old me do? I had a potty accident at their house..)
It was bizarre and sad... thus the friendship ended.
