I only add people I know in real life as friends on steam. So don't bother sending an invite if you've never met me in person. I'll only ignore/block depending on what I see when I view your profile. I don't play online multiplayer games except ones which can have private instances that I play with my boyfriend so having a huge friends list isn't necessary nor desired.

You're welcome to leave me a non-creepy message on my profile and I'll respond, and you'll sometimes find me chatting on the discussions for the games I play. But that's the limit of the kind of social stuff you'll find me happy to do here on steam. I'm just here to play games!
