I'm so sorry you're going to die soon. It makes me sad when trucks damage your low hanging branches.

Thank you for giving us oxygen. Thank you for being so pretty.

I don't think that there is much more to talk about as we don't have a lot in common, you being a tree and such. But I'm glad we're in this together.

Do trees have genders? I hope you've had some nice sun today.
