We'll be sitting in the living room watching TV. Her phone will beep, she'll pull it out and look at it and then laugh and say "(niece) is out with her new boyfriend, she is bored" and then start typing away like mad. Sheesh.
You are being naive. Niece's who are out with "new" boyfriends don't call their Aunt because they are bored and then have the Aunt start typing away like mad....
I would guess this is OM and you are being lied to.....
