I've been teaching myself german, which is going well. I'd like to learn arabic or maybe mandarin. Mainly just to be able to understand what people that speak that around me are saying. I know mandarin is a bit difficult because one word can be pronounced three different ways and mean three different things. Along with the letters. Then there's arabic which is harsh and the words are like scribble, as well as being written right to left. German seems like the easiest, but the others are more challenging.
So it's either:
German
Arabic
Mandarin
