very crap summer job that i hate

sincere apologies for not having posted in ages. i am not going to give you any excuse.
so i am all finished at uni here in copenhagen and i survived economics.
the reason for this post was to complain about my new summerjob. which i thought would be quite good. i am a sort of janitor person assistant and i get to be outside everyday. which is quite nice. the problem is that the guy i am working for is never satisfied with what i am doing. either i am not doing it well enough, and if i then try to correct it and do it better, i spend too long. it's such a hassle. and then he complains more that i don't do this and that good enough. i really hate it now and almost (actually do) wish i would get fired so don't have to go anymore. but i don't really think i can quit cos i have signed a contract and all that. now i don't wanna go to work tomorrow.
