Alternators and Starters

ok, so for those of you that don't know, I work at an alternator and starter shop. For other of you that know what exactly those are and what they do, well you are way ahead of me. Today my boss decides that I need to learn about then and other car related things so that I can give estimates over the phone and stuff. So he starts out "basic".. there are 3 different groups of both starters and 3 different groups of alternators. I'm thinking ok thats easy enough right.. well alternators either have the fan internal or external and the regulators internal and external.. the newer ones have both inside.. I'm thinking ok ok the fan is obvious, if i can see it its external. Then after a lot more explanation.. that i couldn't even begin to repeat cause he might as well have been speaking another language, he moves onto starters. Then there are a whole lot of abreviations, and each has a whole sentence practically to explain it... and by this point I'm just staring at the computer screen like a deer caught in the headlights. He asks me questions and I'm just silent.. I am so not interested in cars, I turn the key and it goes.. and when it doesn't I trade cars with Jaxon for the day.. I mean thats why I got married! Before Jaxon was my Daddy. So, now i am deciding if I want to try and learn this new language, which lets face it if I still have no idea after working there for 5 months I'm never going to, or just wait out the next 4 months until I get to quit. They knew I knew nothing about cars when they hired me, why now is it an issue? My boss is this weirdo looking guy with a long beard and mustage that half gray.. and this curly mullet thing. He makes no sense and yet thinks he is so good with people. People come in all the time and he will talk to them about there cars for like 20 minutes and then leave.. and they lean over to me and ask what the heck was he talking about? Not cause they have my sickness of lack of knowledge in the car department.. but because he rambles on and on and has no social skills. It makes my job so hard I have to quess what he is asking me to do, and then if i try and verify what he really wants me to do, he says well yeah this is whats going on we will go from here, and his favorite line is "so on and so forth" and he doesnt know how to use it! Anyways my job is kinda funny sometimes.
