dating and his kids

I once went on a date with my steady man and his two teenage daughters. We got to the restaurant and ordered our meals. Then the one of the girls pulled out her cell phone and proceeded to talk on the phone to some friends while we were waiting for our food. She did not stop even when the food was delivered and even dialed another friend when that call ended.
I thought this whole display was very rude and just figured she was a stupid person who was clueless about social graces. I also thought both her parents were slobs for not telling her what was proper behavior at the dinner table. I also thought her father was a spineless moron for not telling her either, off to the side that evening, or politely while she was in mid-phone dialing to the next call, to put the phone away for at the minimum 15 minutes to be involved with the company there at her table during dinner.
Well, I googled her name just out of curiousity a while back and found that she has been on the deans list at some college on the east coast for three semesters. So I guess I was wrong about her being stupid, she's just a rude jerk.
Glad I don't have them in my life.
