You scrable to your feet, making more noise than necessary, and run out of the room. This pulls Peter out of his meditation. You look back just once, in time to see him looking forlornly after you.
You never return to the store, and you never see Peter again.
That's it! You've missed your chance to talk philosophy(or perhaps do a bit more than talk) with the one and only Peter Tork!
You dum-dum.
