There are some good reasons or examples as to why it can be good to visit the model's friends.
In fact, I have a very good one:
I visited Model A and we get on great, had some private shows and have an amazing laugh if I can, helped her understand some things (either about the site or abbreviations or other English words she is unsure about) - she is a great English speaker,r reader and writer, but obviously, she doesn't know all the shorthand and slang.
Anyway, she had a friend starting out on the site (SC) and she asked me if I could visit her and talk/tip etc and welcome her to the site, helping her with little bits if I could.
I did it purely out of kindness, to begin with as I really like Model A, but I also grew to be really close "friends" with Model b too.
(There was never any awkwardness between any of us as Model A was happy that I liked her friend too, and those 2 talk all the time and tell each other everything)
Obviously, had Model A not told me about Model B, I most likely still would have found her myself but I would never have known they knew each other so I never would have had the desire to try to find them.
