Life is

Life is a ball of string,
you never know when it'll end.

Life is a daytime sky,
it can be bright, but also gloomy.

Life is the time,
it may seem to go quickly, but really it's a fairly long time.

Life is a face,
it can be filled with smiles, or filled with frowns.

Life is surfing a wave,
it's so far over head, that it's out of your reach at the same time your on top of it.

Life is a ball of string,
you never know how long it'll last.
