bloody psycho arsehole on the bus this evening

I'm 6' 4" and I cannot sit in the buss seats which are designed for people half my height so this areshole forces himself down next to me on the bus, pushing himself into me so I'm practically pinned into my seat for the whole journey home barely able to read my book which helps me pass the time, and then when I try to get out to get off at my stop he goes on at me for not talking to him! Why do I get all the bloody psychos?
