How much pain has been caused for lacking of knowledge, lack of sensitivity or selfishness, mentioning only the less severe errors. Better not think of physical or sexual abuse. There are major words.
Make a mix with on one side, a sensitive temperament little kid and a caretaker or caretakers who aren’t ready to give the kid his/her own place and you will have a soul roaming all life long.
I’m happy I won’t have kids bc I seriously doubt I would have done things very different.
I’m happy now parents know more about how to take care of their kinds much better than in the past.
