I can understand where you mention "triggering", I was a volunteer teacher aide from 830 to 1230, then was attending college part time, glad I switch to animal studies.
I volunteered 5 yrs Mon thru Fri. and witnessed a lot of negative stuff, bullies and the dumb parents that encouraged it and defended it when the problem was addressed to the kid's parents, the parents needed discipline way more than the bully kids. It tore my heart to even witness them bullying my son. I didn't want to do it but I brought it to the principal and teacher's attention, not just for hiim but the other victims of this nightmare so many kids deal with, ruining a kid's life from 1st to 8th grades. He was so happy in the HS he went to when we had hubby's job relo, it worked out great, he is now in his 2nd yr of college on scholarship and has terrific grades.
The upside working at the elementary school years ago, was the sweet kids, the serious students and their fantastic parents, that was the enlightening side.
Many of the bullies later grew up to be hoodlums/losers and their parents still defend them or cop out with some excuse.
All I can say, "enjoy your kids, spend times with them, go on weekend outings, even if it's just a walk in the park, we all grow old fast, life is short, live every minute to the fullest.
Bless you all
