I was on public transport this morning going to airport (I went to a major city in UK) to come home, a guy was sat and another walked past accidentally hitting the guy sat down with his bag, the guy sat down made a remark about what had happened and the guy standing apologised, sat down guy said "you will be" I processed to step in which sat down guy wasn't happy with, I just told my Mum and she said what if he had a knife on him? I just didn't think and thought I should step in by saying he didn't mean to do it.
I'm rambling sorry.
