There are people who long to conceive so many years after getting a full licence to live together; and there are people who undesirngly and accidently are forced to carry anunwanted child.
Its a biological function, two homeless people could have a kid, its not something that makes someone special, if anything people who have kids that they can't support on their own are a drag on the rest of us.
It's a gift. Sometimes people don't understand the gift, but it's still a gift nonetheless. I had my first child very stupidly at 19. But I loved carrying her and never felt resentful toward her. She changed my perspective on life, and she continues to bring me joy and laughter.
