I was on the coach to go home from London this evening when an old man got on at the last minute with his wife. There were no seats left to sit together at this point so he starts making a fuss and refusing to sit down anywhere. In the end, the lady sat next to me offers him her seat where there is a free seat behind so he can be sat in the seat in front of his wife. At this point the bus is already in motion as we've set off. So the lady next to me gets up to give him her seat and just as she's about to take her new seat the bus judders causing them all to almost fall over as none of them have yet to take their seat. So I'm thinking, great, now I have to sit next to this man who's causing a disturbance to everyone because he won't just sit down in an available seat. He starts to elbow me whilst he's sat next to me as he won't stay still which was really annoying but I just tried to ignore it as best I could and sit right up close to the window to try to avoid him. In the end he reaches to get something from in his pocket whilst giving me a massive whack in the chest with his elbow which made me so cross that I picked up my bag to put it in between us to act as a barrier to which he crossly picked up my bag again and put it back on my lap. So I said to him, ' You just elbowed me in the chest!' And he said, 'Well it's going to happen from time to time' So I just said, 'I would appreciate it if you didn't elbow me in the chest, thank you very much' and I put my backpack on my front so that if he did it again he would hit the bag instead of me. Am I being unreasonable? I understand a bit of light elbowing on a coach ride but he had his elbow permanently in my side before that happened and by this point I was sick of him not keeping himself to himself.
