#1. Don't derail a game on purpose.
Ex. A picture of something you dislike. You would type what you saw. You may be negative about it, but do not completely change the subject.
#2. Don't make any cute doodles, only spooky doodles.
Ex. A description of a cat. You would draw a scary cat, even if they said it was cute.
#3. Cute descriptions are fine but remember the next person is going to have to try and make it dark. Ex. A doodle of a spider. You could caption it with "Spider." or "The cutest wittle spider I ever did see!" Both are fine.
