is this seat taken?

What you ask when you are late for class

and the only desk left is up front 

or

when you have multiple bags

and a backpack

or 

when you are in a hurry and the stewardess is staring at you 

or

when a table of four has only

three people

or

What I asked 

when I saw you and wanted two of those people to disappear 

^{thx for challenge}
