Happiness is simple, sometimes.

Happiness is simple,
when you see your mum waiting for you with a smile on her face when you reach home.

Happiness is simple,
when you knock on lover's door and she immediately opens the door and gives you a hug.

Happiness is simple,
when you watch a nice movie with your lover and hold her hand tightly.

Happiness is simple,
when you bought yourself a nice book.

Happiness is simple, sometimes.
