What I said is very embarrassing. The many years ago. At school in the evening after school. I and friends think to deceive friends for them I go home now. And was going to surprise in the end.But when will appear to walk up the stairs to pretend friends are waiting for me. I walk very fast. I tripped on the stairs, I pretend friends failed. But shame. Is there are lots of people in that area.But what I'm happy is to help a loud laughter of my friend as well?
