Oh

When you are discontent, you always want more, more more.  Your desire can never be satisfied.  But when you practice contentment, you can say to yourself, "Oh, yes - I already have everything that I need."

~ HH the 14th Dalai Lama

Oh

 

It can be a sound of realization.  Pleasure.  Fear

A question or the introduction to a disagreement.

 

You can bend it to convey lots of different things depending on your needs, wants, emotions, circumstances. 

 

You can do the same with with other sounds...

 

"Ah"

"Hm"

"Huh"

"Juggernaut"

 

Of course some are more flexible than others.
