Open door

You use your weight to keep the door shut and your might to finally turn the key, your hand starts to sweat and your heart starts to beat faster. You feel like you're running out of time but you're not giving up. You keep turning the key and finally the key is fully turned and the door shuts with a loud bang. But another door of another abandoned classroom door fly open but your friend threw the other key towards you and you catch it and quickly closed it but it was difficult to hold it closed.
