It's what the man says

I want to swim in the hot tub, why can't I swim too? whined my niece's two year old son. 

Because it's the rule.

 But, naming his siblings, they get to swim, why can't I? 

I'm sorry honey,  come to the edge and lets put your feet in, 

Just as he scoots to the edge of the hot tub to dangle his feet in the water a young life guard walks over and reminds my niece the rule about small children not being allowed in the hot tub. 

 Pregnant with her fifth child, she gives the young man an exasperated look and told him perhaps her son would listen to him if he explained the rules.

Making quite an impression on the little boy, he finally got it. 

'The man says no.' 'The man say's no.'

 Over and over he would repeat, 'The man says no.'

Months later my niece and her family were visiting my sister in California who happens to have a hot tub attached to their pool.

My niece enthusiastically showed her youngest son the hot tub and told him he could go in.

The man says no, he replied.

But grandpa is the man now, ask grandpa.

With all the courage and hope his two year self could muster, he looked at his grandpa and asked,

Man, can I swim in your hot tub?

'YES! his grandpa answered.

Jumping for joy the little two year old shouted, The man says YES! The man says YES! 

Then the whole family broke out in unison, 'The man say's YES! The man says YES!
