Caller ID, while a convenience for some, has caused a lapse in phone manners. I don't have caller ID on the phone I usually answer. I've recently had a few calls where the caller just starts talking without any identification. I'm then left with trying to recognize the voice without letting the caller know I have no idea who they are.
I can understand close family members not identifying themselves, but I think other people should just say, "Hi, it's so and so", then get into the conversation. It's embarrassing to try to stall until I can identify the voice.
Or, maybe I should start using the other phone.
