This is my son screaming to amaze or wonder on the top of his longs. (verwonderen in dutch).

But he is confused because he thinks he is screaming: ‘Van onderen’. Sorry for the dutch.
This is a term they use on building sites, when there is danger of something almost falling on you they scream: VAN ONDEREN.

At this time I really like this position from both angles.
To keep wonder and amazement in your life.
Although you have the feeling you have to duck down for safety a lot of the times.
