Ever notice how many people on the phone, when it's time to hang up, say "Mmm bye." I don't know where that Mmm comes from. I doubt folks even realize they're doing it. It bugs me for some reason. It bugs me a lot. I talked to Comcast and my doctor's office yesterday morning and both people said "Mmm bye." Why can't they just say goodbye or bye? It's the Mmm that I can't understand. I've asked a few foreign friends and they say it's an American thing and you're not likely to hear it in the UK or Canada. Of course I don't call many people in the UK or Canada.
