Rain! Rain! go away

Once upon a time, three people were sitting across a table while one of them remarked,

The house opposite to the garage is getting a new roof today. But its raining. They don't even have anything to cover. Must cause problems, I fear!

'Why the hell have they planned it when they very well know about the cyclones in the city (Well, a south Indian city with an international airport. Guess madi..) for the past 3-4 days?', said the other one.

These people see stars, planets, comets before doing all these. But they can't see the clouds around. Foolishness of the highest order, uff!.

'You know what?', he continued, 'you are not supposed to have a haircut on Tuesdays, not eat non-vegetarian food on Saturdays; god where are you! If you are killing animals to satiate your hunger, then why this concession on a particular day?

But I make it a point that I go for a haircut only on Tuesdays. I save a lot of time that way!', he chuckled.

'Age. It all comes with age. Only then will you realize the importance of all this. How old are you?', said the first one.

Now the one who wasn't involved in the conversation was steadily smiling looking at neither of the others' faces.

There was silence for a while and then they all got up and went away.

And by the way, they lived happily ever after!
