You are joking right? There is space for one more person between “him” and her son 😅. Must admit, for a small ass, but there is space! Plus if that bothers “you”… there is always an option for the mother to swap with her son or ask to swap completely with the person. P.s. it’s not your bench, people can sit on the same bench if they like. She didn’t say anything about him being inappropriate. It’s a cultural thing she’s talking about... which she can’t expect people knowing.

I don’t think her issue is as much about the close proximity of where the man is sitting but the fact that the soles of his shoes are facing them. She’s not complaining just pointing out that in Japan, that is considered an insult
