T-shirts vs. Shirts

Ah, I remember being the one who argued against shirts and in favor of t-shirts because I hadn't worn a short-sleeved shirt even once back then. However, now I've also come to appreciate them, so I know they're a great thing. However, I haven't changed my opinion; from a convenience standpoint, t-shirts are the absolute best. Unfortunately, due to a number of reasons, I almost exclusively wear shirts when I go out.
