  At the doctors office this morning : Right after having been given a harmless diagnosis for the yucky stuff on my pharynx (in my mind, I had made up lots of worst case scenarios already) by the nice doc sitting in for my usual ENT, I ask him: "So what do you think has caused this? " "Well, there are several reasons: it could be a low immune reaction, or this or this or this (sidenote: forgot it all already, I confess) , or it could have been caused by mechanical irritation. " To which I died laughing. To which the nice doc blushed. And said something about dental procedures. But that really couldn't save the moment and omit the first thought I had. Oh, how I wish it *could* have been caused by "mechanical irritation". *smirk*
