How to Get Unfriended

In the over 7 years I have been on XHamster, I have only unfriended a handful of users. But here is how you make the cut. I had sent a complimentary IM to one of my friends in the morning. She responded saying thanks and she couldn't talk. Later on in the day I saw her back online and sent her an IM. Well, as you can see her response was less than cordial. I assumed since we were friends she would know who I was and, if not, simply pulling up my profile would have refreshed her memory. In any event, such a rude response told me that I did not need her as a friend.
