Hmm, that makes me remember a situation I found myself in at a shopping mall recently. After dumping the kids off at the pool, I was just wiping away the bits that wouldn't go away when I experienced a breakthrough in the cheap toilet paper. "Bugger!" I thought as I carefully cleaned under my finger nail. It is one of those things though where you can never be sure if all the remnants have totally been eradicated, so after I had travelled about 10 meters from the toilet door, I decided to sniff my finger to see if it stank like shit. At that moment a very hot, young Japanese girl spied me, and rolled her eyes away, with a look of disgust.
What I want to know is, how can she be so sure that I was sniffing my finger to see if it stank like shit? I think it is wrong for people to assume that just because I may be sniffing my finger I am checking for a shit smell.
I noticed in "Star Wars" episode I during the Jedi meeting to decide Aniken Skywalker's future as a Jedi, that Yoda is sitting, looking very sage-like and sniffing his finger. Yoda's a seriously respectable figure, and for him to sit in a meeting of leading Jedis and sniff his finger would suggest to me that it is a socially acceptable practice.
What do others think? If you see somebody sniffing their finger, what is the first thing you consider they may be checking for?
