Sorry for the ridiculously small post, but its late and I'm tired.
Water. I like water. It's pretty, and very useful.
Err, Neptune was the Roman god of the sea, Poseidon is the Greek equivalent. There are many other water gods and goddesses, as well as monsters and dryads and so on that lived under the sea and in rivers and lakes in mythology. They're pretty interesting so do look them up.
Sometimes water carries disease.
So to end on that positive factual note, thanks for reading this. Again, I'm very sorry for this poor post.
