Hello Dear,
I am writing this letter to show my gratitude towards your kind step of returning my driving license.
As i drive daily by my car,carrying the license is certainly a must thing for me.I was very tensed for loosing it.In addition driving without it will have many legal consequences.In fact I had checked every possible place where i would have been dropped it but all in vain.
I was going to apply for new when I heard from you.
It was a great relief getting it back and on the same time i was wondering where you found it.
I would like to invite you over coffee for you have gone an extra mile just to return my license.Please tell me about your availability so that i can make necessary arrangements.
waiting for your reply.
warm regards,
Smith Joe
