Is this weird?

My fiancés “new” coworker texted him earlier a picture of her daughter’s gashed knee and so he showed me.

When I asked who she was, he said she moved from one location in the store so now she’s a new hire on the met team and she has a son his age who also works there and a daughter that’s 9. He then says yeah, that’s gross (or whatever) remind me not to open that up again. When I looked they had other previous messages but I have no idea what was said or if he even texted back. He’s very discreet with his phone and I don’t get on it much.

Like why is she sending him pictures of her daughter’s knee? That’s so random and weird. I don’t even know my coworkers ages or kids ages like that and this is a “new” girl and you already know her like that or something to be receiving pictures??
