What's in your Head?

The call comes. Dad, I am at Autozone, What kind of oil do I need for my car. Now that’s makes a dad really proud even tho I will be the one changing it. Oh that’s Pennzoil High Mileage 5W-30. It’s in a 5 quart container. What kind of oil filter do I need? Oh that’s a Fram PH 3387A. The wife’s van uses a PH16. My old Z car used a PH2450. Why do I know this? I have a thing for numbers. I still remember part numbers from machines I worked on 30 yrs ago and don’t tell the wife but my old girl friends number(no I don’t call). Past addresses, phone numbers, and dimensions of parts I made a long time ago still hold spaces in my noggin. Wooohooooo, My mind is a trap. Then the wife calls, Did you pick up little A at her friends?? Uhhh no. Did you get your prescription filled?? Uhhh No Did you pick up the dog food at the vet?? Uhhhh No Crap. I am not totally forgetful, I do remember to brush my teeth and shower in the morn, but I have headed off to work without shaving and my glasses and my work laptop a couple times too. I think I need to dump and defrag to make room for more current useful things. What fills your head??
