When our children were younger we would send them off to day camp with a water bottle in hand. My oldest decided they didn’t want to carry a full bottle so they only put a little water in the bottle as a norm. Well they learned the hard way why you need to drink a lot of water on hot days when you’re playing hard so you don’t then pass out. What they told me that they actually learned was, when you’re holding on to something and pass out you let go and fall to the ground, yep, gravity. When my spouse arrived to get the children she avoided the ambulance figuring to give the people their privacy, unaware they were looking for her, surprise.
