Being next.

The rush when you realize that you are next is one of a kind. 

This feeling is very exciting, very universal. It never gets old.

Being next in the queue to get your french fries. 

Being next in the line for the roller coaster. 

 Being next at the railway station ticket queue. 

Being next in the waiting line at the dentist. 

Being next on the day of the university viva exams. 

Being next in the hierarchy of office promotion. 

Being next when the sorting hat puts you in one of the Hogwarts Houses. 

Suddenly being next feels anxious, feels great.
