Tom arrived at the bus station quite early for the London bus. The bus for London would not eave until five to twelve. He saw a lot of people waiting in the station. Some were standing in lines, others were walking about. There was a group of school-girls. Their teacher was trying to keep them in order. Tom looked around but there was nowhere for him to sit.

"What time is your bus?" asked John.

They talked while drinking. Then Tom looked at the clock again.
