You and Björn had been friends for a long time. You'd always hang out together and most of the time Björn would be at your house.

You knew a lot about eachother and one of the things that you knew about Björn is that he was scared of thunder.

Today, you were at your house, Björn was at his own house when it suddenly started raining very hard. After a little while there was a rumble in the sky.
