I always take an umbrella in case it rains. Let us buy a chicken in case Peter comes. In case I forget, remind me to check the tyre pressure before we load up the car. I'll fill up the car with petrol in case you need to go to Brighton. In case of fire, exit from the building by the stairs. Do not attempt to use the lift. In cases of difficulty, phone this help line. In cases of emergency , contact me .
