This may have happened before, but to the best of my knowledge this is the first Unfriend I’ve experienced!
I posted something which one of my (now former) friends found controversial and offensive, and there ensued an argument over the subject. All OK so far, but then she said that I had posted something not credible and offensive. So I told her that she had no idea how many times I had had to beat my head against a wall trying to keep myself from responding from things she had posted that were offensive and not credible.
All OK, right? Well, she didn’t like that, and suddenly all the little name attributions FB puts on people’s posts turned from linkable to just plain text. I checked, and yes, she was gone from my friend list.
I am heartbroken!
Not really. But I do regret hurting her feelings.
