Draw a counterclockwise circular arc from alpha to beta degrees

Sometimes it was even spinning around twice counterclockwise, once clockwise and peck the key twice.

But if you go around, if you were to split it half way like this, or maybe another better way to think about is if you were to go around this molecule in that direction, the counterclockwise direction, you would encounter a CH2 group, and then you encounter a CH2 group, and then you would encounter a third, and then you would encounter a fourth CH2 group, then you would come back to where you were before.
