(Inspired by another thread)
Yes I know there are far more annoying occurrences on train.
But yesterday, on the way home from work, there was a child (age 10ish) sat behind me on the train eating crisps and munching very loudly with their mouth open. He was sat next to his mother (I presume) who said nothing.
Would I be unreasonable to tell them to chew with his mouth closed?
Btw I genuinely have misophonia and noises like that make me rage/want to cry
