Where's Martin tonight? He's gone to the pictures with a friend. What, again? Yes, I'm afraid so! That's the fourth time he's been out this week in the evening and yet he complains that he's behind with his studies and getting poor results. Well, it's his own fault, he shouldn't go out so much. He should stay at home more and work. He should invite his friends here instead of going out. No, not here! His friends are so noisy, they're always singing, dancing and playing music at any time of the day or night. It's impossible to sleep when they come round.
