      Because the only brainfuck instructions in your comment where a - which decrements and 20 +, each of which increments.
      Mine echos the first two characters from stdin, because of the commas and dots.

      it’s been a long time since i looked at brainfuck, but i suspect that ‘+’ denotes an increment, and ‘-’ denotes a decrement, so we’ve got one decrement and 20 increments.
