One of my co workers is pissing me off ?

Well it started the smorning this geezer is 67 and I was working when I chucked some stuff in the bin and I dropped some stuff walking to the bin so I threw they from where I dropped it and cause it was card board is drifted off and nearly landed on old ones head it he just shouted out loud "U FU***n T***" and just said "sorry mate" he said "yeah fin ****" and I just said "ohh chill out" anyways some time later I was praised by my assistant manager about a parcel that I packed up well and it was one I packed up before I broke up from work for a fortnight and the old guy said "it's cause he didn't pack it" I just said "what is your problem" and I've got no answer from him he's starting to really piss me off should I just ignore him all together
