So I'm thinking of picking up a foreign language next semester...

What do you guys think? I could do a higher-level French class (Good to retain what I know, possibly the most useless language to take, though) or Spanish (useful as all get out, but I'd probably just mix it up with French), or Hebrew (good if I go to Israel next summer like I'm thinking about, and I already read it and speak a tiny bit), or Mandarin (probably the most "useful" next to Spanish, but I doubt I'd get much use out of it and it's supposed to be tricky to pick up) or Russian (Really, all I want to do with my life is learn how to read Cyrillic, because it looks awesome.) course sign ups for Speaking Freely don't go up until fall semester, so I've got a while to think on this, but I'd like some opinions. So! What language should Aliza learn next semester?
