If people don't want kids its really their choice and i couldnt care less!
But yes i am happy not everyone doesent want to have kids, there wouldnt be much people in about a 100 years :P
Im 23 years old myself
I do want kids myself, infact im preggers! If i'll be a good parent? i hope so, and i'll defenitly try, being a good parent doesent come before having children anyway. but i've learned a lot from my parents and being alive. i've also learned from my parents what i won't be like
