Really. I don't even care if the comment has to do with what you just read. Maybe you could tell me a story. That would be nice. Or give me an idea to write about, you could do that if you wanted. You could draw or take a picture and post it. I'm just throwing out a few ideas here. The possibilities are endless.
Don't be afraid or self conscious either. I won't judge you. That's not true. I will judge, but I don't know who you are, so it really doesn't matter.
