I promised to be there

If one day you feel like crying... 　 Call me.
I don't promise that I will make you laugh,
But I can cry with you.
If one day you want to run away -
Don't be afraid to call me.
I don't promise to ask you to stop...
But I can run with you.
If one day you don't want to listen to anyone...
Call me.
I promise to be there for you,
And I promise to be very quiet.
But if one day you call...
And there is no answer...
Come fast to see me,
Perhaps I need you.
