On the way back from dinner tonight, I noticed that a woman opposite me (across the aisle) on the train was quietly but audibly crying, sniffling.
There was also a woman sat directly opposite her, with headphones in who didnt seem to notice. I also had headphones on but could still hear.
I didn't ask if she was OK or anything because I didn't think it was any of my business, and thought she might just want to be left alone. (I probably would). But now I feel bad for not checking she was OK. Aibu for not saying anything?
