WaT iS tHe wOrSe tHiNg A PaReNt CaN Do tO ThEiR ChIlD???

I FEEL THAT THE WORSE THING THAT A PARENT CAN DO TO A CHILD IS EMBARSS THEM!!! EMBARASS THEM IN PUBLIC OR INFRONT OF THERE BOY/GIRLFRIEND OR FRIENDS PERIOD!!! THAT MUST HURT REALLY BAD!!!
THE 2ND THING I THINK THE WORSE THING A PARENT CAN DO IS NOT CLAIM THERE CHILD OR NOT LIKE THEIR CHILD. I FEEL THAT IF THE PARENT DOESNT LIKE THE CHILD THEN THEY NEED TO GIVE THE CHILD UP INSTEAD OF ABUSING THE CHILD OR HURTING THE CHILD PHYSICALLY OR MENTALLY!!!
