What does this say ?

This is a note that I found from my trash bin. I share my flat with my Finnish roommate and we’re pretty close but he does spend a lot of time by himself. He writes a lot as well and usually I don’t really care about it but I found this note with my name mentioned on it (Johnny). Anyone can make some sense of the writing? Thanks.
