Write a Letter to a stranger thanking him for sending you back the bag which you had lost.

Dear Sir

Words fail me to express gratitude for returning the bag which was misplaced yesterday in the bus. The bag contained Rs. Eighty-two. I found the money intact in the bag.

Though the amount was not big, the gesture of goodwill is extremely praiseworthy. The bag contained very useful and important documents too and I have found all of them intact.
In this world, goodness still exists and it seems that there are quite a few good people like you.

I express my heartfelt thankfulness to you and I extend an invitation to visit my home. I will feel greatly honoured to receive a person of your nature.

Yours sincerely

Your Name
