Waiting for baby is like...

Waiting for my wife to go into labor and deliver our first baby is like...

Imagine signing up for a mission trip to build an orphanage in Turkey and the trip coordinator can only give you an approximate time when the plane takes off. You could book your own flight but he doesn't reccomend it. You know it's a great cause, you feel called to do it, you've been reading all the handyman construction books, your passport and visas are all up to date. It's all the anticipation of a working holiday. You feel sick because he might come in the middle of the night, while you are at work or asleep when the call comes:

3 am
*RING*
(groggy) "...hello"
"Geoff, it's time"
"..huh? who...OH! TIME!"
"see you outside in 5 Minutes, buddy."
*CLICK*

And off you go!
