Ah yes. When I was your age, I stood on my father´s shoulders too.
And he stood on his father´s shoulder too.
His father also stood on his father´s shoulders.
But he didn´t stand on his fathers shoulders, because he had a bad back.
But this one was the first to stand on his fathers´s shoulders.

Strange thing is, that there were no trees here all this time, so we have no idea, how this tradition started.

our tradition is just the bad back

Why is the taller, heavier, and most likely stronger one on top?

Because it makes for a better pic

I see

(the one carrying is the father so it ads a layer of reading to the picture... And also I thought it would look funny)

I totally missed that detail.
