No voicemail…don’t call back!

Why do we call back numbers who don’t leave a voicemail? 

I made a telephone call recently and when I got an answering machine, I realized I’d dialed the wrong number.  I hung up, dialed correctly, and had a great conversation.  About 20 minutes later, the phone rang and a woman asked:  “Did you call 615-202-xxxx?”   I explained that I had realized my mistake when I heard her answering machine and hung up.  She then hung up on me.

I’ve come up with three reasons why we call back unknown numbers:

1) In our information deluged society, we fear we’ve missed something important, so we call back to make sure we are ‘in the loop”.

2) Curiosity gets the better of us.

3) We can’t stand not knowing who tried to call us.

I’ve made a commitment not to call back numbers that don’t leave a message.  If it was important, they’ll make sure they connect with me.   Why do you think we have this compulsion to return phone calls when they don’t leave a message and we have no idea who they were?
