When Did That Happen? (Another Puke Stain)

     It's freezing in our building today. Luckily, I opened one of my cabinets and found a sweater I left there. After wearing it for an hour or two, I noticed a large, slightly yellow stain on my left shoulder and down my sleeve. Yup, it's throw up. And, it's definitely a very old stain. Put it this way - I can't remember the last time I wore this sweater, probably when it was still chilly out last Spring. It also means, when I wore this sweater into work - I walked around the whole day without realizing I had throw up on me (because, had I known, I would have taken it home and washed it).
