Bet my lucky find would be a toothless guy who just wants to tell me about his cat.

You mentioned the tree seemed healthier with more habitat birds and less stress on the trunk, but I wonder if that's just wishful thinking. A big dead limb on a mature oak can rot and fall at the worst time, maybe on your roof or a car. I've seen trees where leaving dead wood let in decay that spread down to the main trunk, and then you're looking at a removal job that costs way more than a simple prune would have. Plus, birds will nest in live branches just fine if you leave the canopy thick enough. Pruning isn't about being perfect, it's about keeping the tree safe and sound for the long haul.

I'd be more worried if you found a working router in there honestly.

My stick figure meetings are getting way too detailed lol

Did you ever try boiling your pasta in something other than water? I did it with chicken broth once on a whim and it was life changing, even my picky kid ate seconds. Kinda makes you wonder what other basic cooking rules are just total myths we've been blindly following.
