Because I will get it.
When my kids were smaller, I would beg them not to answer the phone unless they promised to take a message IN THE MESSAGE BOOK.
I think they usually meant to, but mostly I would find little scraps of paper while digging around in the pencil drawer, informing me that
"sistr ranbow needs u to call hr emedeately."
Who is the message for? Date? Time? MONTH? I'd even take a MONTH for a reference point. But no luck.
Consequently, more than one of our family councils had an agenda item completely dedicated to phone messages, and to making the children pledge NOT to answer the phone unless they were willing to take a proper message, in the little book, and fill out all the little blanks.
Our next try at getting our messages was to instruct the children to say to the the caller "My dad will be more likely to get the message if you leave it on the answering machine. Would you like to call back and I'll let it go to the machine?" Which was a perfectly viable option, because, really, as a caller wouldn't you rather just call back and infinitely improve your chances of actually getting your message through?
It worked for awhile.
The kids figured out that they could screen calls, and not even answer the ones that they weren't for them anyway. (Hint- 99% of the time it's not for them, so even if they're standing next to the phone, they don't answer it.)
Except that we then figured out that we all hate checking messages on the answering machine. I've written about it before.
So the Brain set it up for all the messages to come to me as email. I set it up to automatically forward the messages to his email.
So I guess where I'm going with this is that if you ever call my house, I am the only person who ever answers the phone, and if I'm not here, you can leave a message nobody will hear.
No wonder all my friends are imaginary.
