The light and dark.

I have one hand it cannot clap
All it does is fall and flap.
But when one hand it turns to two
Then clap I can, and clap I do.
I can play tennis on my own
But that's just stupid all alone
And tennis is so much more fun
When you can play against someone

A candle burning gives off light
That best can be seen in the night
If candles just burn in the day
Then sunlight lights their light away.

A rainy day though not much fun,
Helps us be thankful for the sun.
For in life it’s opposing things
That give us joy and give us wings
