I have left my umbrella home

http://jjenv.com/tag/55-gal-drum/ I have made it a thrifty custom, to take my umbrella with me each time I leave.
I use it to balance my walk,
I use it to watch my road,
I use it cover my grief,
I use it veil my smile,
I have used and will use it in more than a thousands of miles.
But only for today, and only on this one way road,
I left my umbrella home…
