Go Back Throw back!

so i am writing this because starting this blog made me think about this old memory that ties to my whole blog. anyways where i come from every girl hopes to please their parents by marrying the guy of there dreams and then having a couple kids to raise and  calling everything good, right?? well some of the other girls i knew all had made little goals for themselves such as "being a "COOL" mom!" or to "Never repeat the same mistakes that they watched their older siblings or parents make." and just stuff like that. but anyways at that time my whole take on life was set on becoming a mom whether i was cool wasn't what matter. But being a mom did and all that started at a young age. so i guess my Question is if society has placed an age limit/restriction on when it is okay to be a mom, why is it so tied into how we are raise? just food for thought.
