Why Moms Have Gray Hair

My son went to the Bahamas for a fishing trip.  From all reports, and pictures, it would appear that it was a fun, successful trip.
He sent along 18 pictures, many of them beautiful views of the local color.
One, in particular, of Eric diving for conch.

The pictures truly told the story of the trip.
Doesn't Eric look happy with that conch in his hand.  It became part of their dinner later in the day.

Then, the kicker.
In the same water where Eric went diving for the conch, he takes and sends this picture.

He tagged it as 'shark'!
My son is diving in the same water where sharks are circling. 
This is why Moms never know what is going on until after it is over.
