It is a blessing from me

It's a blessing on St.Patrick's day,
For every tear, you will get a joy
For the darkness, you will get the light
For gloominess, you will feel all right
For all the things that are in your heart
You will get that pleasant start
You will get lucky oh my dear
So have that smiling face with cheer
For it will surely be fun for you
Wishing a happy St.Patrick's Day to you!
