Yesterday in my MCAT class my teacher asked if anyone had any tylenol, advil, etc. I said, " I've got excedrin migraine (only the best headache medicine ever). He said, " That's be great." Not even thinking about it, I popped open the top and put two in my hand and gave them to him. He said thanks and then went to take them.

Later in class when the material had lost me beyond the point of return, my mind started to wander. " Jenny, you are so gross." my mind said. " You just put two pills in your hand that someone else was going to put in their mouth! Why didn't you just hand him the jar and he could have had as many as he wanted without the pills coming in contact with your nasty hands?" I don't know why it didn't occur to me. I just hoped it didn't occur to him that I am the grossest person ever and I hope when he left the room after I gave him the excedrin, that it was only to get some water, and that it was not to run to the bathroom, vomit, then scrape off the top layer of pill because I contaminated it.
