Think of haiku as today's equivalent of a tweet, in the sense that there's a fixed number of characters you must stick to in order to convey an idea. Instead of 144 characters, you have 17 syllables to make an impression.
Poetry can carry a lot of emotional weight. Its lines can wade through deep territory and cause you to ponder the very things you try to avoid thinking about on a daily basis. It can open a wound or illuminate a small experience, making you grateful for having read it in the first place. But there's also something to be said for the lighthearted, and I think we could use a little bit of that today. This haiku is about the "glossy tender bean" edamame, and describes some of the humor involved in eating them.
