You do realise how this is making you look yes? Dragging it off for a troll to try and justify making an 8month pregnant woman stand? Know what kind of "man" you are
I am not trolling I am genuinely asking why you refused to vacate a seat and instigated a confrontation when you could have aimed to address the situation in a more amicable manner. I am not justifying making an 8 month pregnant woman stand - I am not justifying the flat refusal to vacate a seat which was reserved by someone. If it is as you said you should have had the presence of mind to sort something out when boarding the train.
