Just got the idea. Just say something like: something you want off your chest, or something that you hope Bloo will see and put in her signature, or a favorite book that you want to let people know about...
My friend Cassondra and I have somehow started an inside joke, that I am a robot and she is an alien that created me, and that she programmed me into thinking I am human.... Random enough for ya?
Thats a good start! You just reminded me of something. Me and my friend started pretending that we were aliens. Our other friend wanted to become an alien as well, but he had to pass a test. So we lead him all around our cove, but we never let him pass. We did it for a few days and then let him be an alien. After that, it wasn't fun any more.
