i speak english (obviously) and speak spanish pretty well. my vocabulary is still a bit limited but i can understand people and can usually get across what i want to say. it's pretty useful here, but i wish i spoke more. i would want to learn mandarin since that's probably the 3rd most useful language here after english and spanish, but i have picked up some books just for the speaking part, not even writing, and it is reeeeeeally challenging.
