Actually it seems as though neither of us is wrong or right, as it states it is a matter of taste.. I was tought in my school that using commas in that way was evil, so I guess that was my teachers' taste.
That's beside the point anyways, which was that constantly giving someone crap about that stuff is unneccessary and just creates a bad atmosphere, like there has been far too much around here recently. If you find that kind of stuff funny when it obviously affects someone then I doubt there's much anyone can do for you.
