Your mobile starts ringing. you answer it hurriedly. Its your Mum. She
asks,"Where on earth are you. Your friend Micheal is coming over
to tea." You had completely forgotten about tea. You quickly
reply,"I'm in a bit of a muddle. It may take a while to explain.
Bye." You speedily switch of your mobile. You and your friends
run to the end of the hall you are now in. But which way should you
go, left or right?
