Ocean Wave Rule

Some calls that are defined to start from facing couples (#6)
can also start from a right-hand ocean wave (#8).

What do such calls have in common?
You find yourself in a right-hand ocean wave near the beginning of the call!

So ...
... if you hear the call when you're already in an ocean wave,
just complete the call!

Examples:
Right and Left Thru Square Thru	Pass Thru Slide Thru	Box the Gnat Double Pass Thru Pass to the Center

Right and Left Thru from a Right-Hand Wave

(an application of the ‘Ocean Wave Rule’)

When you do a right and left thru,
you (momentarily) have a (right-hand) ocean wave.

So, if you start in a right-hand wave...

... and hear the call ‘right and left thru’...

... just finish the call with the courtesy turn!
