I decided to use my two free passes for a romantic date with my girlfriend, Jane. I knew she loved animals and I was told they had a small amount of freedom in the zoo so she wouldn't mind that much, and so that night around 6 we pulled up in the car park.
When we got to the main gate, the guard briefly stopped us. "The zoo closes in an hour." he said "We lock the gates at dusk whatever happens. Believe me, you don't want to be locked in overnight."
"Leo, do you have a watch?" asked Jane as we walked in
"Yes, but I think it's running a bit slow." I replied "I think the batteries must be going. Never mind, there's bound to be clocks all round the place, and they'll announce closing time over some kind of speaker system or something. Anyway, forget about the time, what animals do you want to see first?"
