Noisy neighbours
Julie always thought of herself as an easy going and (dull/glad/quarrelsome/tolerant) person, who put up with
people's differences. She hardly ever became (upset/helpful/fascinating/careless) about anything, and believed that if
you treated people well, they would (scream/like/co-operate/mind) with you. That is, until Alex and Harry moved in
next door. At first, when their music woke her in the night, she was just a bit (furious/irritated/annoying/thrilled), but
did not feel (realistic/guilty/conscience/offended). She shrugged her (shoulders/arms/hands/head) and said to herself,
“Never mind, I make a lot of noise sometimes. I'll go round and (cry/quarrel/complain/fall out), in as nice a way as
possible.” When she knocked at Alex and Harry's door she said, “I'm not very (interested/like/happy/keen) on loud
music, to be (loud/honest/upset/nervous). Do you think you could turn it down a bit?” They just
(whispered/cried/waved/grinned), and then Alex said, “You can think whatever you like, as far as we're
(concerned/determined/decided/embarrassed)”. Then they shut the door in Julie's face. By the end of the week, Julie
felt angry, but was determined not to (have/lose/shout/break) her temper. She had hardly slept, and kept
(blushing/snoring/yawning/growling) all the time, but she kept busy. The next time she called next door, she gave Harry
and Alex a present. “It's just a cake I made for you. Please (accept/take/attempt/invite) my apologies for last time!'” And
that day the noise stopped. “What a (believe/naughty/shame/relief),” thought Julie. “Now there's some peace and quiet
and I can read my favourite book The History of Poison ...”
