Pool portrait 2 - Who is the star?

Another hot 33 degree celsius day on the Gold Coast & so it was back to the pool to again cool off.

The question I'm going to ask you today is who is the star of this photo? Is it my nephew or his grandfather (& my father)? I had a tough time trying to decide & I came up with different reasons to support both views but ultimately the two of them are enjoying the moment & maybe that's the reason why this photo works well (in my humble opinion of course!).
