Truth.
Especially when things are grim.

One of the reasons i love tolkien is the theme that despair is an enemy
and it makes clear you don’t need to have constant hope, you can get by with grim determination or spite but never despair
and it makes clear you don’t need to have constant hope, you can get by with grim determination or spite but never despair
You can be as terrified or nonplussed or unperturbed as you like; the sun will still rise tomorrow & the rent will still be due on the 31st. The world has no romantic narratives for its fate except those we invent, because the world does not die. That is our privilege.

Holy shit, the wolves came down to Boulder metro, Louisville and Lafayette, and into Erie last month!
Other than cars (which are a huge threat) I’d rather they be down here. They’re very good for controlling coyote populations(which we need) & they’re less likely to get shot by a whiny ass rancher.

Yesterday, when I was leaving work I had to pull over and grab this photo — cause the clouds above one of the old radio telescopes at work looked really good. Puffy blobs sinking under their weight.
This is Remus 📡
I’ve stretched the image a little by increasing contrast, and foreground shadows.

Just a murderous fungus having taken over a wasp and compelled it to die in a place advantageous to finding more victims. With its tiny spores floating off through the air in hopes of just one landing on an exoskeleton.. nothing in the rainforest wants anything to do with this little scene here…

Brilliant thread on how to handle the big, difficult holidays.
I’m 16 years post-divorce, 2 years post losing my Mom, 2 months post losing my SO, and am having Thanksgiving for the first time with my ex, her hubby, and our kids.
It’ll go well, I deeply appreciate the invite, but I’ll be careful.

Okay, so you cannot avoid a Thanksgiving event, and it’s not entirely under your control. You’re home from college, you live with your parents, your spouse isn’t ready to process how awful their natal family is. It happens. THERE ARE STRATEGIES YOU CAN EMPLOY TO YOUR BENEFIT.

Because people keep asking, the Story of The Lizard In That Dude's Leg. Some caveats:
1. This happened more than twenty years ago. There are no pictures. There was a small article in a local paper with, again, no pictures (I'm assuming that's what the producers of 9-1-1: LONE STAR found).

Maybe the airlines should stop double booking seats, adding fees for baggage, splitting up families who don’t pay extra for seat assignments, stuff like that. That would improve the mood in airports.
