"Over heeeeere!...
Over heeeeere!..."

...and the challenge continues. Only this time, it's a mental one.

Reversal vs. Retrograde:

In a reversal,
-en dehors becomes en dedans (and vv.)
-front tendu becomes back tendu (and vv.)
-croise REMAINS croise (efface REMAINS efface); consider these relative directions as anchors, or constants in an otherwise topsy-turvy, discombobulating scenario

In a retrograde reversal, the film rewinds. Everything (ie: the variables listed above) remains constant, but the order of events reverses. Don't bother with this type of reversal in ballet class-- at least for now.

In a combined reversal + retrograde reversal, the shoes end up on the head, which internally combusts.

-a concept class, where the power to turn comes from the hips using compression (the plie) and torsion (twisting of the hips with the supporting foot stuck to the ground)
-feeling dumb is a precursor to getting smarter; acknowledge the confusion, then sort it out.
