What is wrong with people!?!

👉Angela👈 • My whole world is my 11 year old son and my 3 year old daughter. 😍
We were at my son's school for movie night and most of the kids were running around, playing, having a good time. My son was laying on a floor mat, watching the movie, and minding his own business. Next thing I know, this little girl, maybe 4 or 5, charges up to my son, starts yelling at him, and then starts stomping on him with her foot. My son is too nice and won't say anything or tell an adult, and her damn mother was just sitting there allowing this to happen! I had had enough and walked over and grabbed the little girls wrist, got in her face, and told her if she does it it again, I'd take her to her Mom so she could take her home. The Mom had the nerve to get mad at me for putting my hand on her. I told her she should probably teach her child not to be a bully and then things like that wouldn't happen! I was, and still am pissed off! Why do parents allow this stuff to happen??
