Tornado get dressed (a) ,,,. More coffee For road (a) ,...., drive ...I should have had breakfast....maybe I'll get a smoothie before work ( a) yeah nah .... I can wait till lunch to eat then ,.,,,. Work .... Smile and act like I'm listening to morning chit chat with coworkers before meetings start :) think about what I'm gonna do when I grow up while they talk,... Wait..... I should already have grown up ... Well I'm never gonna grow up then :/ ..maybe I'll move to Van finally and take that job ,.... Nope I won't ... Maybe I'll go to Toronto then ,... Um to late you going next week sucka ... Now I really just don't wanna go grrrrr .,..I really wanna get a puppy but I can't even get my life together enough to match up my socks in the morning .... More coffee .. Yessssssssss:) and thats all before 9 am on a weekday. And I missed some (a)'s. That's how my thoughts works ... I'm guessing I'm not the only one just different details and less (a)' s ;p
