The Half Finished Tipi

There's a giant tipi which is half finished;
Huge tree trunks a meter wide and a hundred foot long all stacked up
together in a flat field. I feel the need to help finish this tipi
project, but when I start using leverage to get another couple of tree
trunks hoisted up to the apex , one of the trunks crashes to the
ground nearly crushing some of the little people below.

With this trunk down, a couple more of the giant trunks come crashing
down, one of them snapping in half as it hits the ground.

The force of these falling trunks down causes the fastening holding
all the poles together to dislodge, which then allows many more giants
to crash to the ground. The little people run in all directions to get
away from the danger. These falling logs will bring an end to anyone
they hit.

I feel I should have known that if I put up the poles it would have
collapsed, and now I feel really bad for causing this danger and
potential death to the little people.
