the seat hoggers

Now we all know these people, whether it be in class or in the metro, the people that put their shit on a chair and don't move it no matter what. whats up with these morons? do they not want their precious school bags to get dirty? i mean come on, i know that sometimes girls buy expensive bags and all that but when i come to class late and there is no where to sit and your bag is occupying the lone empty seat that there isnt a human being in (which is what chairs are meant for by the way) move it the fuck out so i can sit down. and dont be all annoyed by it either, trust me i dont wanna sit beside you either but i didnt really have a choice. in class is one thing because it rarely happens that there is no where to sit i must admit. but in the metro its really a big deal. there are approximately 12 seats for every door in the metro and there are approximately 1000 people in each cart (number of people may have a slight exaggeration). you do the math, or are you not smart enough because your bag is sitting there on a seat where I or someone else lucky enough to see it first can sit. its rare enough to actually get a chance to sit down in the metro and then out of no where theres this mirage of a seat with no head in it and you are wondering why there are people standing up all around it, and you think wow they are just all strong people who dont wanna sit down so i'll take it. and of course you go there only to see a fucking school bag sitting there and the owner of the bag sitting down comfortably doing homework and listening to their ipod like nothing is going on. i knew people wouldnt be standing around an empty seat but i had to go check anyways just to get pissed off cause of this seat hogger. whats the idea behind it anyway? all i can think about is the not getting the bag dirty. is that really it? cause if it is its really dumb, if its something else let me know. im just here trying to make the world a less annoying place to live.
