My buddy did that once and the other driver gave him a real dirty look.

Remember reading about the guy who invented the traffic light. He was a policeman in Detroit who got tired of watching carriages and cars crash at busy corners. His first design in 1920 used red and green lights and a buzzer. It's funny how a lot of safety stuff comes from just one person seeing a dumb problem and fixing it.

Oh wow, that sounds like a total nightmare... I can just picture the green spray everywhere. Avocado is so stubborn, it's like it stains on purpose. I had a similar thing happen with a smoothie explosion once, and the stain never really came out. For tiles, maybe try a paste of baking soda and water first, let it sit for a while before you scrub. Good luck, that's a rough one to deal with.

Patking said the good ones are all about real connection. That's part of it, but it's more like a work group. The one I'm in makes you show up with a real business problem each month. Then everyone picks it apart and tells you what you're missing. It's not just making friends. It's getting a bunch of other business owners to point out the obvious thing you're too close to see. That's what helped me, not just the networking.

My engineering school still uses a 1980s K&E slide rule for some intro classes.
