I don't see it that way at all. She is not celebrating that she had the child, but rather that she had the child and still continued her education.
A friend of my daughter turns 15 this week - her mother was 16 and single when the child was born but had to drop out of school. Mom had been raped. I truly wish she had been able to finish school. I truly can not stand the woman and consider her a leech on society, but she, some where along the line, did something right because that (soon to be) 15 year old daughter has become something her mother will never be - a respectable and productive member of society.
I see something you, in your sentimentalism don’t see. There is something pathological about this type of single mother, a narcissistic distortion in their personalities that causes them to seek out these situations where they can act the role of the victim.
She is already using her poor child - using him as a prop in a drama that’s all about her - which is why she didn’t get an abortion or give the baby.up for adoption - then she wouldn’t be able to.continue her drama.
I can tell you if that had happened to me in high school, in a million years I would not have displayed my child as my accomplishment. The idea is sickening.
