John seems to be looking for you. he texts you on PesterChum many times while you were busy or asleep, maybe just tried to ignore him? was afraid to answer...?

most of the time he mutters for himself something like:...

John: keep calm..

so, John is your best friend from kindergarten and you guys always spent a lot of time together. the next time you didn't answer him in PesterChum, after half an hour you heard a knock on your door. I guess he's really worry about you...
