I once went away on a business trip to San Francisco with another guy. We agreed that the next day, a Saturday, we would walk round San Francisco.
I woke early about 8am due to time zones differences so got up and went for a short walk on my own.
Got back to the hotel and knocked on his door about 9am and he said he was not ready.
Went for a longer walk on my own, and got back to the hotel about 10:30am, and he still was not ready.
Went for an another walk on my own, and went to his room about 11:30, knocked on his door, and he let me in and he was still in his pyjamas.
We eventually went out for our walk about 12:30.
To this day I was wonder what he was doing all morning.
