I Wanna Split This Room In Half

I had a bad day.I went to work at 8 a.m and I finished at 4.15 p.m. Two hours of extra-work(my contract is for 6 hours total).And guess what? Tomorrow morning ,if we can call it like that,I've gotta get up at 4 a.m! 4 a.m shit!It's not even a different day! That's insane,it's driving me crazy. I want to spend my lifetime doing something else than stay at the airport.My books are full of dust because I'm too tired to study when I come back home. The most annoying thing is that after you work really hard ('cause the people at the check-in aren't enough) the boss comes to you saying :"You've made mistakes and I'm really pissed off". Everything I wanted to say was:"Well,asshole,first of all,you can't understand what does it means to check two flights at the same time,and if you know it and you keep being pissed off,the way I've just called you completely fits you.Second,I hate this job and if you keep on being annoying I'm gonna make you fire me 'cause I'll loose my shoe in your ass"...but I didn't,I'm too classy and by the way,I have just few days to work,then,fuck the check-in. They're really not a lot of days but everyday is getting harder....
