Good morning on this wet-to-wonderful Thursday.

Class is back in session for more than a million public school children today.

For high school students, especially, this is a time of self exploration, growing pains, and, for those of us reflecting back, some regrets.

We recently asked our readers to share some of the things they wished they had done differently in high school. Here are a few of their regrets:

“What I wish I could’ve done differently: Listen. Be more aware of the potential signs of depression or bullying. I don’t believe I was an aggressor, but I participated in my fair share of it, so I wish I was more self aware, too.”

— Sachin Arora, 29, Astoria, Queens

“If I had to do high school over again, I’d leave aside the ice cream scooping and McDonalds customer service jobs for work that helped me figure out my longer term career, if at all possible.”

— Suzanne Grossman, 42, Maplewood, N.J.
