Every week a courier brought bouquets of roses sent by a person unknown to you. He did not say his name, only left a note with a compliment in the bouquet. At first it bothered you, but after a while such attention became very pleasant.

Today the courier handed you a bouquet of roses again. As you closed the door, you smiled as you opened the note. «I invite you to a restaurant. Come tomorrow at 6 pm, if you agree. I'll be waiting.»
