Minding your own business, sitting alone, a stranger strikes up a conversation. Nothing terribly important, just a short pause from the mundane waiting of life that cannot be avoided, and the insatiable need for human contact and communication, no longer able to be avoided. Well... by them, because your ass has twitter and aim mobile, text message and the whole dam internet on your wi-fi enabled laptop adding machine with full battery power and the wish to enjoy a little quiet.
You guessed it..
You've found yourself in an airport, awaiting a connection, and apparently that means you want to talk to people. At first thought, it's easy to simply say you would politely decline the conversation, and feign tired, or sick, or 'Ich spreche kein English'... we rarely do. We often find ourselves simply giving into another's need to chit chat. What we say however often is up to us, and where todays (not that it's time sensitive) moral question is posed:
Do you have to be truthful to the person in an airport that chats you up?
Seems simple enough. They ask you where you're from, what you do, where you're going, and if you've eaten... do you REALLY have to tell them the truth?
In reality they are talking to you to escape their own reality, they want a story, they want entertainment from anothers life. Why not oblige? If you are willing to talk to them in the first place, then you have already given into their request to entertain them. Besides, telling them you are on your way to another library filing system seminar, really doesn't entertain like that time you had to escort the prince of Zambia to the airport bathroom only to be tackled by his security because they couldn't speak english.
So... don't feel bad spinner of tales, just remember, they asked for it.
