I actually got my appetite back this evening. Too bad I lost it shortly after. I found a frozen brick of beef gulasch and heated it up. Unfortunately noticed shortly after the first few bites that there was a piece with a capillary sticking out of it. Thus my appetite disappeared again.
My mood is on an upswing though. I talked to my grandfather today, and he convinced me to enjoy my youth. Then Kerstin promised me that Vienna would return to its full glory again when she returns next week.
Maybe there is hope for the rest of the summer!
