Look at that picture up there, now how difficult would it be to learn all of those words? I bet most people could do it in half an hour. It's only 35 words, after all.
And yet, people tend to have a strong reaction to different languages. They give you the look. I don't mean the befuddled look of incomprehension, but rather the 'how dare you address me with your alien tongue, begone from my presence or I shall shoot hate-lasers from my eyes' look.
Why is that? It goes far beyond frustration at the inability to communicate, so what, exactly, is wrong with speaking a different language?
Languages can be intimidating, especially if you've had little to no exposure to anything other than your mother tongue, and humans have a bad tendency to react to fear with anger.
