He is not coming back

The guy who used to work like a machine, dance for hours without feeling tired, the one who stood up to everything he saw unfair...

He is not coming back.

After a few years of parenthood, he is more irritable, prone to anger and a bit wider than before.

He waits a bit more, he is resigned not to go to the top in short time, he is a bit more careful with his energy.

He is, after all, older. 

This guy has had to accept that others before him have now the upper hand. That he is still seen as different. That his father before him did not have the choice (or the temptation) to bit his lips and walk away from battles.

He is finding satisfaction in achieving the mundane. Happy to wake up and accept bad moods. Happy to be able to cook a meal, be with the children for a while watching the television, and leave early or dissappear to take a nap. 

So he is not coming back...to his old ways.  He simply can't.
