Actually... I would like to have kids. I think two or three, a little girl and two boys.
To be able to watch them grow up, and teach them as much as I can. Until one day as they're leaving the nest, to look back to when they were in diapers, to their first crush, their biggest mistakes and how they learned and grew from then, their first job, teaching them to drive, that time they threw a party while me and their mother were gone for the weekend and almost got away with it... on that day, when they leave, I will be both indescribably proud and astronomically depressed.
But... it also depends on what my future wife wants. I'm not the one who has to go through childbirth!
Of course, if our two became a four or maybe five that means... :3
