Some friends are playing in the field. One of them has a birthday tomorrow. He told all his friends that tomorrow is my birthday and you are invited to my house. My house is located on the road that goes south of this field. If you go a little further, you will find two 3-story buildings. Then you will find a 4-story building on the 2nd floor of the 3rd floor. If you ring the bell with your elbow, I will open the door. Friends then wanted to know why ring the calling bell with the elbow instead of the hand? Then he replied that you will have a gift in hand then how to ring the calling bell?
