Nope. I recognized it immediately, but wouldn’t have been able to spell it from memory. Maybe it was a name that just looks similar? I looked through my high school yearbook, and though I can pick him out in several photos, and he signed my book, he doesn’t appear in the official mugshots and I can’t find his last name anywhere in the book. He just signed his note “Bart”. I could absolutely be misremembering the spelling of his name, or I could have heard something shades different than what he was actually saying, never having heard a word of spoken Polish before meeting him.
