All d teen's out der...i need ur comments on dis one.."TEEN PREGNANCY"?

I am reading a lot of s*** about dis teenage pregnency thing..which according 2 me is sick..i mean how can someone even think about getting pregnant at 14 & 15 yrs when u r not fully matured sexually...mentally...emotionally...i mean wtf...its great 2 be having a kid..but i dont understand how some of you actually feel proud about having one at a young age lik dis..i mean what if ur guy starts 2 move on in life..u wud be left alone wid d kid n m sure u wont feel proud of it @ dat tym..dont u feel its better 2 "OPEN YOUR BOOKS AT THIS AGE THAN RATHER SPREADING THOSE LEGS"...i need ur comments on this one...whether u agree with me or not...but if u dont...i need a reason why?
