What Was I Saying?

My mind tends to wander when I'm leaving voicemails for people.  After talking for a few minutes I'll often realize that I'm not entirely sure what I've been saying or if it even makes sense.  As a result, I'm pretty sure at least 72% of the people I call and leave messages for while at work hear something like this:

I wonder if, when people listen to these voicemails, they can easily recognize the exact moment in time when I realized that I was, in fact, leaving a message.  Usually, as soon as that light bulb clicks on, I hurry up and say something like, "Yeah, so, give me a call please."

I wonder if I've ever interrupted a really cool story I was telling someone's voicemail and they were disappointed and wanted to hear the end.
