Tree Rings

Son, come over here and look at the rings on this tree stump. You can learn a lot about the life of a tree from its rings. Count out from the center, and each ring represents a year.

See here, that darker ring around year 22 means the tree survived a forest fire. And, here, where the rings are so skinny around year 34—that was probably a drought. Or, it could be the tree had just gone through a divorce and was trying to “get back out there.”

Notice how this ring has a pink tinge around year seven? That’s probably when the tree went through a Hello Kitty phase. Everything had to be Hello Kitty. And, here in the teens, where the rings are all banged up—that’s when the tree was getting into fights after school under the bleachers.

Look at this ring around year 13. See how it has a rougher shape and is thicker towards the valley wall? That’s the year the tree’s parents got divorced. That would explain the fights at school. But, this thick ring in the mid twenties. It learned how to love again. It met a nice pine in grad school.

Oh look, around year 29 the rings get super porous and then thin. That means the tree got promoted to Senior Manager. Good for it! I’m sure the tree busted its roots for that.

But, after that the rings get very light at cracked. The tree and the pine were starting to grow apart. That happens. I hate to say it, but I’ve never known things to work out between a birch and a pine. Different priorities.

Ahh, look. Just after its own divorce the tree decided to get artificially pollinated, and it had a sapling. It must have been hard nurturing a bud all on its own. That’s lovely, though.

Look at this ring—the really fibrous one. I’m pretty sure that means the tree met a tall oak at a single parents support group. And, they hit it off. Look how healthy and wide the rings get after that. But, the tree still loved its sapling very much, and it would never choose the oak over its sapling…

Honey, you get that this is a metaphor, right? I’m trying to tell you that Bob and I are getting married.
