My friend Vernon Davies kept birds. One day he phoned and told me he was going away for
a week. He asked me to feed 1 birds for him and said that he would leave the key 2 his
front door in my mailbox.
3 (fortunate), I forgot all about the birds until the night before Vernon was going to return.
What was worse, 4 was already dark when I arrived at his house. I soon found that the key
Vernon gave me could not unlock either the front door 5 the back door. I was getting desperate.
I kept thinking of 6 Vernon would say when he came back.
I was just going to give up 7 I noticed that one bedroom window was slightly open. I found
a barrel and pushed in under the window. As the barrel was very heavy, I made a lot of noise. But
in the end, I managed to climb 8 and open the window.
I actually had one leg inside the bedroom when I suddenly realized that someone 9 (shine)
a torch up at me. I looked down and saw a policeman and an old lady, one of Vernon's neighbours.
"What are you doing up there?" said the policeman. 10 (feel) like a complete fool, I replied, "I
was just going to feed Mr Davies' birds."
