What do you call transsexual women?

Ex-men.

The trees on the side of the hills

There is this forest of oaks that grows in a hilly region.

Now, here's the thing: the trees on top of the hills, they grow pretty fast.
The trees at the bottom of the hill, down in the valley, they grow less fast, but still, fast.
The trees on the sides, though, have the slowest growth rates.

Why?

Simple.

They are slope oaks.
