This is going to sound strange. Three time out of four, as I'm getting out of the shower and drying myself, I notice I've omitted to rinse the soap off my right ear. This is odd, as I'm meticulous about rinsing soap suds off everywhere else. It's almost as if I have a little line in my ROM that says 'please forget to rinse right ear so you will then have to get back under the shower when you've nearly dried yourself off'.
Not exactly vexing, but curious and annoying nevertheless.
