Haiku

I got this idea on a forum I go on. It seemed like fun. Here is my first try:
***Edit: OK, I admit, I didn't do the correct research. A Haiku has five syllables on the first line,
seven on the second, and five on the third. This isn't a Haiku at all, but I like it anyway.
I'll work on it.***

Late night
All alone
Completely happy
