Do you find it annoying when someone is over your house watching a movie and they're talking on the phone?

My mom thwarted my cleaning and drinking plan.
She was taking my kids to the movies and decided to stop by my house with the kids while she waited for the later movie to start. Which is ok.
We ordered a pizza and we're watching a kid friendly movie on Amazon called "touched by grace" but she's sitting on the couch talking on the phone, we've missed half the movie with her talking someone please shoot me alread
