Actually a combination of a couple of these items happened during my first period class. My Dexcom reciever kept going during my first period class — I teach computer science so random beeping always disturbs the class.
I pulled out the receiver and said, "whoops, I’m high". My kids said that was the first time a teacher ever said that to them, and it was the first time that they realized it probably wasn’t a good thing.

You say that you feel “high” in public and then wonder why people around you give you weird looks.
