Available

So, just now, I completely ignored the person knocking on my door. I have no idea who they were, I just know that at that moment I didn't feel like chatting, especially as once you start, you really have no idea and only a marginal amount of control over how long things will go.
I completely could have answered. I can also frequently answer my phone when it rings, or respond to the IM that just popped up from the program I forgot to log out of. I just frequently don't.

I do feel kind of bad about my hiding method of avoiding momentarily unwanted interaction. I'll usually even freak out that somehow they can see through the electronic device and know that I'm right there, willfully not answering, because at that moment I have better stuff to do.

I feel like this is something I'm supposed to feel worse about, like there is some unwritten rule that if someone unexpectedly pops up and wants to chat, by golly, you chat with them whether you want to or not. Meh. Apparently I'm socially conditioned enough to know that I should fee bad, and be concerned about hurting peoples feelings or making them feel like I never want to talk with them ever, when really I just didn't feel like it at that moment. Just not enough to actually feel bad. All in all, I'm pretty ok with it. Maybe it's just the introvert in me, but I don't feel a particular obligation to be available all the time, even when I actually am.
