I am passing many people during my daily life. I see so many faces, so many men, so many women, all passing me, going to work, going home, walking around.
I think with myself, what if one of those who passed me today is dearly loved by God and I just passed without giving any salutations.

Diogenes of Sinope, a Greek philosopher living in 4th century BC was famous for his often numerous but thought provoking ways.
Once people found him holding a light in his hand, carefully walking in the busiest area of the city looking for something.
People asked him: "What are you looking for Diogenes?"
Diogenes replied: "I am fed up of animals, am looking for a human being!"

He said, "You are not mad, you are not appropriate to this
house"; I went and became mad, I became bound in shackles.

    He said, "You are not slain, you are not drenched in joy";
before his life-giving face I became slain and cast down.

    He said, "You are a clever little man, drunk with fancy and
doubt"; I became a fool, I became straightened, I became
plucked up out of all.

    He said, "You have become a candle, the qibla of this assem-
bly"; I am not of assembly, I am not candle, I became
scattered smoke.

    He said, "You are shaikh and headman, you are leader and
guide"; I am not shaikh, I am not leader, I became slave
to your command.

    He said, "You have pinions and wings, I will not give you
wings and pinions"; in desire for his pinions and wings I became
wingless and impotent.

    You are the fountain of the sun, I am the shadow of the
willow; when You strike my head, I become low and melting.

I was very busy today, trying to answer so many e-mails waiting in my Inbox before being able to go through my usual long To Do List. Just in the middle of it my son jumped in the room: "Dad can we go cycling?" 
I gave him the obvious answer: "Later!"
He asked again and I replied the same again.
I was finishing one of the e-mails that suddenly it occurs to me, Why?! Why by default my answer to him should always be "Later!"? The e-mails are always there, the To Do List never ends, but how many more years my son might come to me and ask me to go cycling with him?
I closed the laptop (the e-mail was not completed yet) and said to him: "Let's go". ...

... The wind was playing a music in my ears while my bike was going fast downhill. I could see my son just a short distance from me happily trying to control his small bicycle while occasionally turning back his head to make sure I was following him.

And I was thinking, this, this very moment might be the happiest and the most fruitful moment of my life.
