One of my mates got me a notebook for my birthday and it says "happy thoughts" on the front, what I've been using it for (other then drawings) is very... well see for yourself
Ahem..
1: I wanna die lol
2: hail Satan
3: when we die we won't be remembered
4: stop feminists so we (girls) don't get drafted
5: work on the kitchens to poison mens food and have the girls to ourselves
6: turn my cat into Satan
7: write a good story about a cult (don't ask)
8: build a concentration camp
9: find the reincarnation of Hitler and trick him into making me world leader
10: it is called hentai and it is art (if you know the meme you deserve a gold star)
And that's not even the best ones
