Should I do the bonus skills(Idioms/Proverbs & Flirting)? My German friend says germans dont know how to use idioms/proverbs, and I don't want to do flirting.
I agree with BirgitAsh and BobThomas12. Even if you don't think you'll need it, it could quite possibly come in handy many years from now. Even if you don't ever use them, at least you'll know them. It couldn't hurt to just learn it all. Also, you could teach someone else, if that someone did want to learn it. :)
