I meet a lot of nice people, study went well too and was almost happy. But then suddenly out of nowhere dark clouds overlap the sky.
I change my main field of study from chemistry to biochemustry *break for the nerd scream* in the next semester.

Your guess is right, it's philosophy *dramatic music*

Its part of my "ethics for scientists"-module and it hate it sooo damn much you wouldn't believe it.
