Me, looking for the bar: "No. Do you?"
Person I just met, who has immediately judged me as pathetic or selfish: "Yes. 2. Would you like to see photographs?
"Soooo... why don't you have kids.?"
Me, wanting to smack that look off his face: "Don't want them. Why do you?"
Person I just met, confused, because they don't know the answer: "Isn't this shrimp wrapped in bacon excellent?"
This happens pretty regularly with my wife an I when we meet new people. Via Ron Smith, here's a good article on women deciding just not to have kids.
My wife and I make the choice together. We love our lives. We travel at will. We read. We go out on a whim. We also love all of the children around us.
So stop thinking we're pitiful and we're selfish, and turn the question on yourself.
