Det er bare et hopp til venstre og så et steg til høyre.

So "så" doesn't just mean "so"?

La oss gjøre Time Warp igjen!

Og da skal du ankomme til resturanten.

Now slide!

it's the natural course of human nature over man's lifetime

Could I say "Først til venstre, da til høyre"?

Firstly to the left , then to the right. Isn't "First" an adjective? (eg "Usually to the left". Not "Usual to the left")

I was just marked wrong with this (cut and pasted) - I did leave out the comma but DL never cares about punctuation:
first to the left then to the right

How do we know it's the left and the right? First to right then to left was marker wrong.
