I like to play "Are you smarter than a 5th grader?" on my phone at night before bed.
Somehow, I play against strangers. I have no idea where they come from but whatever, I guess it's magical internet voodoo.
As an extremely competitive person, my nemesis is usually pretty clear early in the game and I get all riled up and have to be my quickest, smartest self to defeat them, feeling ridiculously triumphant when it is declared that I am smarter than a 5th grader, and I gloat about being smarter than my opponent and how much it sucks to be them; the loser.
And then I see their avatar picture and realize they are an actual 5th grader. Or really close to it. Maybe middle schoolers. Then I feel a little bit bad. But still good for winning because 5th grade is apparently harder than I remember.
You don't even want to know how I feel when I lose.
