I pick up accents way too easily.
One side effect of mainlining mass quantities of Dr. Who eps close together is that my normal thinking voice has suddenly developed a London accent (at least I think it's London, what do I know?). This would generally be a very cool thing except for my tendency to talk to myself think out loud. Which means that people who are used to me sounding like a New Englander will think I'm even weirder more eccentric than usual.
