A accident. Geeez where do i even start. Well anyways I "was" a rookie driver. This past week was my first week alone. After being on the local sort a position came around so I thought I would try for it. Well i knew it wasn't going to be easy. I knew it was going to be hard, but more physically then mentally. I was totally wrong. I have never been so stressed,mentally exhausted in my life. Hell I was thinking about this earlier, I was putting 10/9/06 on all my paper work and it didn't dawn on me until today what I done. Anyways I don't need to explain to you guys, you know how it is. Well i have had a awful week, coming in @ 8:30 just to drop my truck off with my pick ups and going back out with my res's. Well I have found out No lunch,lack of sleep and 13 hr days well lead to a mental brain fart. Today was like no other day. But it was Friday, and its time to leave the building. K Since i am new at this, I am looking for my truck . At the time i really didn't notice a difference, it didn't dawn on me that my 1200 was switched out to a 1000. Which I really dont understand that, cause I bring in over 500 p/u piece a night and usually the 1200 is packed full. Anyways I hop in and started to take off. "By the way,- I am parked in front of the buildings garage door frame" I usually have to pull up some and back up,pull up,back up then go outside the building for my pre trip. Guess what i really didn't notice i wasn't in the truck i trained in, the all power Cadillac. Blah, so in my routine I put the truck in 2nd, pull up then go to what "I thought" was reverse and started to back up. Guess what, The reverse was total deferent. My stupid butt had it in first gear. The gear patterns are different and i didn't realize it until it was to late. God how can i be so stupid, I know being mentally exhausted had some effect on it but still. I really don't know how i didn't see and feel the difference. I was just in a hurry to get out and get my friggin airs off cause i was one min late on one the day before. I am so disappointed cause I am sure they are going to disqualify me. Maybe for the better. Cause like i said, I never been so stressed and mentally exhausted in my life. Maybe I should have just been a Sat air driver. Dunno, just kind of bummed out.
