As a result I've come up with AnHSL. Andrei & Heather - Sign Language. Contrary to expectations... neither of us really knows any sign language beyond finger spelling the alphabet.
This morning she asked me if I was feeling better. I must digress here that I suffer from "Ravenous Bugblatter Beast of Traal" syndrome. I believe that if Heather can't hear me... I can't talk. (Yeah, I know.. there's logic in them thar hills and those hills are no where near Andrei)
None the less, I get jarred in the morning when she speaks and I can hear her... but such is how my mind sometimes works. </digression>
So, she asks me how I'm feeling. I proceed to draw in the air.
90º turned infinity symbol... She says "8"
circle...she says "0"
A sort of mishmash of 2 circles and a bar... "Percent"
She smiles and gives me a hug
I proceed to then finger write in the air e^i, sigma, integral x-n cuberoot
She's laughing by the time she catches the Sigma.
I love have a geek in the house.
