The key thrust of the analogy: what is the everyday notion of bringing something into existence for measurement purposes then removing it later? Epsilon and deltas? How about photoshopping a camera’s reflection out of its own picture.
You may not enjoy the example, that’s fine, but it’s more familiar than epsilon and delta to most.

Why do we need extra and super-extra silly artificial explanations instead of simply calculating (f(x+epsilon) -f(x))/ epsilon and apply limit epsilon towards zero. What scares me is not this nonsense, it is a free country, but how many people love this thing. This is really scary.

Thanks, I love your 'simplified' ways to make me understand math.
