Being Sure of What You Want

So.

Having a conversation at work, and this gem comes up:

"Have any kids?"
"Not yet. I hope to some day, before I get too old."
"Well, you can always adopt."
"No way. Has to be my blood."

Personal opinion: this guy doesn't actually want children. What he wants is to breed. To each to their own, certainly; but may I suggest that should he consider having a child, he'll be raising a small person and not just a cluster of genetic traits?

Just a thought.
