Raising a child

Two days ago, I was on my way to work. So there was this girl about my age on the bus with a child. The child was about three years old. I guess the ride must have been long for them because both mother and child were getting restless. The mom picked up her cell phone and she dialed the number for the other phone she was holding in her other hand. She handed one phone to the child and they had a conversation. I could not hear what the mom was saying but the child answered the phone: "Bitch, what you callin' my phone for? Bitch!" The mom and her friend thought it was funny. They were laughing and the child, taking it as approval, started to say it louder and louder until everyone in the bus turned to look. A little while after when they were done with the conversation the child hung up saying, "Don't call me again hoe!"
For me, it was a voice far too young and "innocent" to be using language like that.
I sat thinking to myself about the kind of future this kid would have when she got older and I hoped that she would be a little smarter than her mother. I felt as if I cared more for the kid than her mother did and that was sad. I have a low tolerance for behavior like this but it was not the child's fault that she was talking like that. It was what she was used to hearing and she was merely repeating it. Maybe it is just me but I saw something warped there. The thing that was warped was the mother's approval of the whole scene.
Really, my view on kids is just simple: If you don't think you are responsible enough, then please, don't have kids....you will only end up raising a functional delinquent.
