I have been programming in java last week, and I came across very vague instruction behaviour (InputStream.readline() blocking EVERYTHING, despite being threaded). I was looking in the wrong way for a solution (like an observer being blocked by of a mutex and things like that). I was at my parent's house and I noticed I became grumpy. Of course I don't reflect that to my parents (or anyone), other than just asking to be calm and easy because I'm grumpy.
I was grumpy because I was beginning to doubt about my skills.
Eew, a mood swing, it's just so feminine :shudder:
