If they are sitting in the middle between the other 2 trans lesbians they are obviously the switch. Less likely to fight and if involved in a threeway will want to do what is easiest. Usually being the one getting Sammiched.

Whoever is sitting to the North/East/Northeast is obviously the top. Tops are early risers and are going to want to get started before anyone else.
Whoever is sitting to the South/West/Southwest is obviously the bottom. They are late risers and will want to hold off till as late as possible.

So the top being the one sitting to the north/east/northeast going first. The switch sitting in the center bottoming for the top, but the switch tops for the bottom who sits at the south/west/southwest going dead last.

And that is how you figure out how a trans lesbian sammich begins...
Now what were we talking about again?
