Another Weird Thing

I was just sitting here and I thought of another odd thing I do!! I know the alphabet according to which number they are. Like A is #1, J is #10, O is 15 and so forth. What I then do is stare at things (mostly license plates) and see if I can 'cancel' out the all the numbers and letters! I know it is hard to understand. So say the Plate is: CHP 311 - well the c is 3, the h is 8 and the p is 16. So if you add the number you get 5, plus the c (3) = 8, plus the h (8)= 16 !!! Which cancels out the p!!! (16-16=0) I told you it was weird!!!
