If I see a guy walking on water, I am not going to turn away and pretend I did not see it.

I will watch closely, and might evfen ask how it was done.

When the guy tells me how; by walking on the stepping stoes that are slightly submerged:
I do not yell magic, fraud, or trick.

I try it myself.

Then I might ask this guy what else he knows, and try it also.

An outsider calls this magic, or impossible;
wheras an insider class it a skill.

Some skills are unrelated, and might be called tricks.

When there are a set of skills that are related,
this is a QUALITATIVE jump in skill with a new energy or concept;
no trick.
