Why would someone interrupt someone's conversation?

Anonymous

I was talking to this guy at work and he's a little bit younger than I am and as we were having a good conversation the lady next to me that I'm always talking to which is a bit older than I am just up and disappears I don't know where she went but she comes back with a picture from her locker I'm assuming I don't know then she just interrupts me and his conversation showing me a picture of her family then showing him a picture of her family out of nowhere and then she just gets quiet and she looked at me and then looks at him while holding her arm.

It was weird like why would you just interpret us like that it was such strange behavior and she's 62 years old by the way. I don't even really get to talk to him as much. I know she said to me once friends only not girlfriend. Thinking about just pisses me off. This happened to me twice with another female coworker I was talking to him and this girl just interrupts our conversation like I wasn't even standing there, like what's going on.
