The language I think in, as far as I'm aware of (which is not always obvious; I'm not entirely convinced that we think in language, to start with), is the language I'm most immersed in at the moment, so right now it's English. But put me in Québec for a few days and suddenly I'm thinking a lot more in French. But it's not just one or the other though.

I usually keep the personal, non-political stuff for tabnet.
