That's so scary! Glad you're OK.
My husbands Aunt passed away in 2016- she actually choked on a piece of steak, and was by herself. Her husband found her when he got home, but it was too late. Just devastating for the family.
I imagine most people learned the Heimlich in health class, not by their standard subject teacher.
I hope you picked up your daughters tab!!!
Oh my! Sometimes when my husband goes on a trip, I fix a steak. Not doing that anymore.
