My children are currently taking a semester long poetry course. In this course they are exploring the different types of poems, the history of these types, and practicing the types. I remember in high school having a literature course which spent a few weeks exploring poetry. I hated it. I didn't understand how to write metaphorically, but I remember the class. While I have learned to appreciate poetry as an art form and even enjoy some, like Shakespeare's plays, I still don't understand poetry. In fact, for all of my love of Shakespeare, I'd rather read almost anything besides his sonnets. Thankfully, I don't have to completely understand something in order to enjoy or appreciate it.
Appreciating an art form that we don't fully understand is a skill unto itself. Every parent knows that our children will have interests that we probably won't understand. I have a son who loves aquariums and terrariums. I don't understand it, but nothing makes me happier than listening to him share his love of fish. God made this world full. There is so much to appreciate, learn, and explore. Building the skill of appreciation is an important skill for the future parents in our homes. Maybe that's having your child take a specialized math or science class, or maybe it's poetry.
