I see:

 I see:

my son running along the sidewalk.

I think: 

when did he get so tall?

I see:

my son going potty all by himself.

I think: 

how did he learn to do that?

I see:

the furrowed brow of concentration as my son snips paper.

I think: 

when did he become trustworthy with scissors?

I see:

a full-face smile when I greet my son after nap-time.

I think:

how did I get this much joy?

My son is not the first boy to be potty trained.  

They are not the first boys to learn to use scissors or to grow tall or to smile with such abundant joy. 

But it is the first time for me.  Forgive me if I revel in it... if I brag about it... if I bore you with the details... 

I am amazed.
