"Sad" I am sure some cases are as you described. Some could be due to much worse issues....like rape. Even the fact that some made one bad judgment call and got pregnant.Why do girls sleep around so when they get pregnant they don't know who tha baby daddy is?
Even if the Mother slept with more than one man and really don't know who the father is....that is their business! Who says all these babies and Mother's are on welfare?
Are you perfect? Have you ever gotten someone pregnant and don't know it? Have you ever welfare? Or a family member?
