Over the summer I played alot of video games but my experience happened on a game called “Team Fortress 2”

So one afternoon I was on Team Fortress 2 when I got a message saying that a user sent me a friend request. Curiously, I accepted it. I asked if he needed help or wanted something. The user quickly responded back saying “you know what I’m here for”. I told him that I didn’t even know him. A few minutes later he sent me a trade request. I wasn’t surprised because I am an experienced player with a few valuable items. He told me in the trade chat to “cough up”. I thought to myself, “This is getting weird”. So I turned off my PC to take a break.
