The sitting in the airport part is silly, but ultimately harmless.
Yes, it IS ultimately harmless. But at what point do we use these sorts of actions to indicate mental health problems?
Curiously, I look at this and say it is quite reasonable ... if nothing else it is a metaphor for "where do I go from here"
Do I go home?
Do I go back to the combiine?
Do I go to become a priest?
Do I go someplace else?
Any reasonable person invariably (imho) goes through these situations to larger or smaller degrees at some point in life ... or they let life define their path.
Enjoy
