I'm quite sure that certain partners prefer each other, and certain partners dislike one another. Also, I found that someone who dislikes green will NOT pair off with someone wearing a green shirt, for instance; things to keep in mind. I have no regimented experimental data like I do for the food in VV3 (if you call such a small sample 'data') but it's what I've observed.

Heaven help us! Better duck quick!
The clicks are horrendous!
They attack us with glee!
Please help to save us
from the Clicks that run free!
