No.1: Never ask a girl if she is pregnant.
If she is, she'll tell you when she wants. If she IS NOT: RUN AND HIDE, OR YOU'LL GET THE LECTURE OF YOUR LIFE!
No. 2: Never pluck flowers if you're not sure you're allowed to.
Do it, and you might accidently pluck somebody's very rare rose (pft, I so TOTALLY, didn't do that once, nonono)
No, 3: Never pat animals you don't know, before being allowed by its owner or itself.
It may bite you, or just get really aggressive. Watch out for horns!
No 5: Don't read weird stories before you sleep
Seriously, if you're anything like me, your brain will give you the CRAZIEST dreams.
No 6: Always be nice
Always be nice to nice people, because even the nicest of nice people have a limit for their niceness, and you don't want to be near them when they reach that limit.
