Mulling and stewing

So, I've been stewing off and on this year over that subject that had me mulling last summer. It's made me wary of certain people I work with. I just had an interesting conversation with one of the teachers that I know is on my side (because he frequently tells me so) and he had a totally different take on what went on. Apparently, it wasn't an attempt to "get" me, at least from his perspective, and the person I thought was behind it must not have been, but I think someone else was.
Hhhmmmm. More mulling is called for.
(Why do we bother with politics at work? They are such a waste of energy.)
