Physics Professors

I was a table away from a group of Physics professors probably having a meeting in Baguio. They were so nice to overlisten to. Their leader, I presumed because he has white hair, had to ask everybody if they all like local cuisine because they are meeting in a restaurant later. Someone called and he gave the precise location of the restaurant. They checked and rechecked their agenda for their dinner meeting. A few minutes they left. Somebody left an umbrella.
