Strangers

Mama today told the story that happened to her friend.
On behalf of a friend:
Go to the little daughter (5 years), home of the guests. Already late, hurry to get home.
Here is suitable to stop our bus, I have a daughter:
 - Ran rather, it is our bus! Managed Still, climbed out of breath, I sat down on the empty seats, sit ochuhivayus after unscheduled hundred meters.
My daughter is pulling my leg ...
Daughter:
 - Mom, it's our bus?
I:
 - Yes, my daughter, our.
Daughter:
 - Mom, this is exactly our bus?
I:
 - Of course, we will soon come home.
Daughter:
 - Are you sure that this is our bus?
I:
 - Yeah, sure ...
Daughter:
 - Then why are all strangers?
