I started to learn Spanish but I quit when I learned that every Mexican village has its own dialect. There is a different word for "eggs" because Mexicans are even more sexually uptight than Americans. Brands of beer are usually sexual puns so that you can't mention your preference outside the bar.
I started to learn Arabic but I quit when I learned that it is so hard that even native speakers can't get it right.
I started to learn Chinese. The first thirteen lessons were only on how to draw the characters. So I switched to an online thing and learned about two hundred words, but still no idea how to read or write anything. I quit when I learned that China has more English speakers than USA has.
