A ride on a double- decker
Yesterday it was Gretel’s afternoon off. “You needn’t stay in doors ,Gretel,” Mrs. Clark said. ”You like paintings. Why don’t you go to the Tate Gallery? There’s a famous collection of modern paintings there.”
“How can I get there?” Gretel asked.
“You must catch a bus. Number 88 will take you there.”
Gretel loves the red double-decker buses in London. She always sits upstairs and tries to get the front seat. Yesterday she was lucky. The front seat was empty. Gretel had a wonderful view of London. The bus went round Trafalgar Square and down Whitehall. The conductor collected Gretel’s fare. “Tate Gallery please,” she said.” Please tell me where I must get off.”
After a while the conductor said,” Here’s the Tate, Miss. You should get off here.”
“I should , but I’m not going to ,” Gretel said. “ I’m enjoying my ride on the bus. I’ll have to go to the Tate next week. May I have another ticket please?”
