High school reunions run the gamut from wholesome to depressing, and that's just including the ones that happen in person (opposed to drunken Facebook DMs).
If we're being honest with ourselves though, isn't it morbid curiosity and a potential for drama that draws most of us to the spectacle of reunions? Certainly, there are earnest connections to be made, but those are just as easily facilitated over the internet.
However, the emotional hailstorm of everyone from high school in one room is only available through reunions, and even then, there are people missing.
My grandpa invited his English teacher from high school to their 60th HS reunion. She was 97 at the time (101 now) and is sharp as a tack. She had a wonderful time seeing everyone and even remembered a good portion of her students, but did mention that it was disheartening to see students of hers who have died or are suffering from dementia.
