what should I expect for my north/south node return ?
You can expect that as the Lunar Nodes return in their original position, that in this time, you can feel especially aligned with the new energy you are ought to embrace, here, the North Node is like a red, blinking arrow, while the South Node is strong with backing you up with the skill-set and knowledge you already possess.
You could say it's a time in which we can be and are allowed to be opportunistic, because the NN is benefiting from opportunism after all.
The Nodal return thus is said to represent the end of a big cycle in life, hence why it happens when we're around 18 years old and start growing into adults, in some countries it's even the age when you become a legal adult. But whatever the theme is during your lunar node return depends entirely on your NN-SN axis, and the aspects they might make within your chart.
