Apparently just reading about it makes me yawn, like I just did a few seconds ago. XD; Although, I do catch myself yawning when I notice other people doing it as well. Sometimes it doesn't happen, but I see it as a natural reaction. It has actually been proven to be a contagious chain reaction, but many people see it unnoticed unless actually thinking about it. But, yeah...yawning to me is quite contagious, hence I just did it again.
