Psychic Connection?

It seems like practically every time I talk to my mom or sister on the phone the other one will call while we're talking. Or when I call one of them, she's on the phone with the other. I kid you not, it must happen at least 70% of the time. We don't talk all the time either--maybe twice a week or so? And we don't talk at the same time every time. It's just odd.
