Something to ponder...

This girl was thinking today (no smart ass comments please), and she realized that while deidre is very submissive, her sister is quite Dominant. Master’s brother seems to be the submissive type, and, of course, Master is Dominant. So here’s the question. Do most siblings who identify as one or the other have brothers or sisters who identify opposingly? Additionally, If you are Dominant to the 9th degree, do you have a sibling who is submissive to the 9th degree?
