Because they can

Admit it.

 You might get a touch jealous.

In other words,

 you are wondering how they did it,

   and might be feeling a bit angry.

You wanted to do it.

Now,

 someone just wrote something.

You were trying to reach for.

Your reaction is the key.

Slide into anger,

 using criticisms,

  which will sound petty.

Or,

  you think to yourself,

   "That works."

I prefer to avoid being petty.

  Unless it is Tom Petty.

   I miss him.
