Have you ever known someone and you avoided going to their home?

I had a friend (note: past tense) and I hated going to her house and being her friend. It was disgusting. There would be chicken bones tucked in the sofa and she would literally throw away dirty clothes rather than wash them. She would call her children obscene names and hit them with whatever was handy and cheat on her husband. Over the years I tried to sever our friendship but she just would not go away! Finally I just moved and never told her where I lived. Not too long ago she emailed me about a mutual friend of ours who passed away. I ignored the email. I’m puzzled at why this woman wants to be my friend so bad when it’s obvious I hate her. Know anyone like this?
