My family is out-of-town, my wife and son are enjoying a trip to the east-coast, so knowing I was home alone our dear neighbors (who are almost like a second family) invited me over to join them for a nice meal pool-side to celebrate the 4th.
Mid-meal I look up and see my neighbor starting to turn blue. She was clearly choking (but not really reacting). Her young grandchildren were there, but too young to help, and her husband (who is a retired physician) is elderly and has had some physical heath issues and is not strong...so I decided I better act fast.
I've never done the Heimlich maneuver before (and am not trained to do it) but it worked. It was all calmness on my end at the time, but now I'm having one of those "thank goodness I was there" moments. I'm not sure it would have gone well otherwise.
Heavy experience. Maybe a little post-traumatic stress.
