I was out walking today and saw a youngish m/f couple (I'd guess about 15) arguing. The female was really crying and the male looked like he was trying to grab her hand repeatedly - she didn't seem to want that.
Anyway, I walked past and then thought of my own DD and went back and asked the girl if she was ok. No reply. I said "I just want to make sure you're safe, if you would like me to stay with you, or walk somewhere with you then I will"
The male then says "please tell the lady you're ok as this is the third person who's stopped now"
The female said (no eye contact) "I'm fine"
I said "sure?"
She said "yes" so I left them alone.
I finished my walk wondering how I could have handled that better? I was initially buoyed by the fact 2 others had stopped but then I thought that meant the situation was obviously concerning more people than just me.
