I've been creeping this board and have finally decided to make a comment...
uhm, well shit. What was I gonna say. On a humorous note I actually read, write, and speak Japanese at functions for the Japan-America Society of Washington, DC and I have to say, I have no fucking clue what you two are saying. I'm not saying, that you're not saying anything. I'm just saying, that what you're saying is not being understood by me. You know what I'm saying? 'Cause that's what I'm saying.
Then on a serious note, I honestly support what people want to do with their down time. Learning a new language can be looked at simply as a hobby. Something to pass the time and see the world in different ways, bring new meanings to words. Pick up exotic words that have no spoken English counterparts. It's an amazing thing, it can be fun. And I mean any language, I'd even encourage you guys to pick up some American Sign Language, or any other countries sign language.
You only get one brain to cram things in, and you only get it once. <3
