One parenting tip from me: assume your kids will do stuff behind your back, remind them that they have a stack of get out of jail free cards at home: if they get into a bad situation you want them to call you. Make sure they know they won’t get into trouble if they ask for help.

Anyone else kind of hate days off if only because it ruins the schedule?
I want days off. I need days off. But I also get so stressed out when school goes on break.
I tried to explain this to another teacher and I think they reported me to HR for being unwell.

I am on my way home to Toronto and the aurorae are absolutely phenomenal.
If you are anywhere in the northern half of the continent, get outside and look up! Or better still, put your camera on a 10 second exposure and point it up.
