Dateable?

Random thought: whenever my friends are talking about a hypothetical dating situation, to tell a joke or prove a point, etc, etc, I'm always the one who's the girlfriend in the fake relationship. For instance, a group of my friends and I (yes, I have friends, whoah) were talking about how funny it would be if our friend Tyler (who happens to be gay) would post on his Tumblr that he, in fact, had a girlfriend, and see how many of his followers would freak. And who was the "fake girlfriend" in this scenario? Me. I mean, our friend group created this whole messed up family tree where I am in a relationship with probably half of the members... Now, just to clarify, this is all completely silly. I understand we're making jokes, and I probably laugh louder than anyone else because I think it's really funny when people make fun of me (if they're being nice about it. This isn't permission to tear me apart. I have delicate feels.) But, it just got me thinking... Am I always the imaginary girlfriend because everyone finds me really dateable? Or is it because the concept of me dating someone is so ridiculous, it makes the jokes that much more funny? Just random thoughts...
