Sam's(15-16 year old teen) best friend is Sarah now. But Sam tells us that actually they weren't always friends. Only two months ago they even didn't want to hear each other's names. Two months ago Sam and Sarah were invited to their mutual friend Marie's birthday party. Though they were unpleasantly surprised meeting each other at Marie's birthday party, they decided to ignore each other and have fun. But they couldn't. Soon an unexpected thing happened and Marie told that all the guests had to leave the house because she had to go as soon as she could. Everybody left the house with Marie except for Sam and Sarah. They were left alone in the house accidentally. At first they weren't going on with each other but soon they found a common language.
