Oh my god. We found him! We found the one character in EGS who makes excuses when he sees obvious magic and doesn't just accept it as a thing!
Well, that, or he's so jaded that he's not impressed by actual magic, and simply regards sleeves resizing as not being noteworthy.
It wasn't until after I'd written "someone's skateboarding" that I remembered one of my high school friends getting in trouble for rollerblading in a mall. At least. I believe it was rollerblading. That sounds more true to what I remember than skateboarding, but memory is a tricksy thing that cannot be fully trusted.
In any case, I wasn't there when it happened, and I assume the trouble was no greater than "get out and take your sweet roller blades with you", but yeah. People skating in malls is a thing that happens and is not tolerated (short of the mall having a sweet roller rink or something)
