Languages have always been interesting to me. I took two years of French in high school, but none of it really stuck with me regrettably.
I did however, take a year of Russian in high school and two and a half years in college. Due to a lack of use, I've forgotten some of it, and most assuredly couldn't hold a conversation without a brief refresher. I've found that I can still read Russian relatively well though.
Funnily enough, learning Russian completely destroyed my ability to write in cursive in English. Throughout school I was always taught to write in non-cursive text, whereas Russian was the complete opposite in that everything was written in cursive. Even to this day if I try and write in cursive in English I have to focus very hard to make sure that I am forming English letters and not Russian ones

I also wanted to take Farsi while I was in college, but simply didn't have the time in my schedule to accommodate it. I've considered simply auditing the class anyway now that I've already graduated.
French has always interested me as well. I would love to go back to it more seriously.
