I've had a few, and one BFF. ( In the most realistic sense of the term.)
That's if you mean my closest friend at the time, otherwise I've had lots of best friends.
It's not like I don't go outside and do not have a life. I personally feel people cannot be trusted and things such as true friend is rare. I am also confident that I would not have one judging by the condition of life. As for friends, I have some but they are not good ones. I do not have best friends but only mild friends
