It takes forever, can be painful, it's huge, and if you aren't careful, there can be a big mess toward the end of it.
When you're done, you send your elephants out into the world, hoping to see them again at some point. You think about your pretty elephants (the stuff you're proud of), worry about your mutant elephants (the mistakes that you never notice until AFTER sending the damn thing out), and hope neither of them spreads so much poo that no one wants to play with your elephants anymore.
The gestation period is somewhere around forever. One elephant is about two years - but you're carrying a litter!
They're impossible to ignore. I mean, you have a bunch of elephants gestating inside you - it's kinda distracting. No matter what else you're doing or working on, your thoughts keep coming back to those elephants.
I had more to say, but one of my elephants just kicked. Let me know how your elephants are treating you.
