Out-of-town Emergency Contact Details
My friend explained that it's really important to just think of it as worse case scenario. Like, if I was stuck on Granville Island and couldn't get across the water and Julian had to spend the night with his teachers and classmates. She said think of that as I'm prepping the bag and then just forget about it...yeah, that's real easy to do after you write a letter to your child "just in case"!
