Shoulder-barging

Now, I’m a reasonably big bloke, six foot two, 18 stone, part muscle, but predominantly flab (I carry some of it reasonably well, the rest hangs off like a sack of shit). So why is it that so many times when I’m walking down the street in a straight line I have some fucker walk towards me across my path and we end up nudging each other when there is plenty of room for everybody on the pavement. This happens daily. Even old women do it. Am I invisible? Or is everybody just thoughtless, selfish, arrogant, aggressive and downright rude. The answer, most of the time, is yes. Groups of people walking in line abreast, don’t make any attempt to close in or walk in single file, and virtually force me onto the road. I make a point now (unless he’s a big c**t) of standing my ground and keeping my line. I’m not spoiling for trouble, I’m a peaceful chap, but I cannot abide having to deviate from my course because of some fucker with attitude who strays into MY path. They walk AT me. It’s a conspiracy. They are saying, “There’s that Bill Turnip twat, let’s nudge the old git”. I just don’t know why it happens but I’m getting really angry about it.
