On purpose, or coincidental?

So basically yesterday I took this video of my ex-best friends boyfriend, saying that he was gay. Of course it was a joke, so I put it up on fb.(i don't like her at all, i don't know how she feels towards me) But today, she took a video of this guy I used to like saying the same thing. I used my iPod, so did she. She videotaped it after school on the bus, so did I. Then in a photo I tagged my friend's boobs. weird right? well they were kinda out there -____- then she did the same thing, but on a different photo. I need another opinion, on purpose or coincidental?
