Meh. I keep switching between happy and sad. It kind of sucks.

watashi wa genki nai. chipotle wa ryouko da.

butsurigaku no shukudai o oemashita. demo, rikashi no shukudai o oemasen deshita.

The previous statements are probably horribly flawed. It's ok.

ryouko = demon
butsurigaku = physics class
shukudai = homework
oeru = finish
rikashi = lab
