do you ever feed bad when one of your friends of family dont want to have kids?

do you ever feed bad when one of your friends of family dont want to have kids? I feel bad but I dont want to have kids, of course im happy that they get to do what they want and i dont encourage them to have kids because i dont want them to be pressured into it. but i feel bad that they will never have kids because i like them as a person, i think they would make a good parent and I want more relatives, i have a very small family, just parents grandparents and my grandmas sisters, their kids and their kids kids. I wish I did not feel this way because its very ironic.
