Nobody talks about how many of those planes are just cargo jets with no reason to dump anything.

Man, checking it in the parking lot is just a waste of time if you ask me. Those cheap squares from the big box stores are gonna be off no matter how many you dig through, so you are just standing there looking silly testing ten of them against each other. A 1/16 over two feet sounds bad but half the guys I know just tap the thing with a hammer to true it up once they get home anyway. If you are doing rough framing it does not matter, and if you are doing finish work you should be using a better square than whatever the lumber yard is selling.

Did you ever think the handshake might not be the whole problem? I read some thing a while back where a dating coach said the end of a date should match the vibe you built, so if it was flirty and fun you go for a hug or at least a light touch on the arm, and if it was more chill then a hug still works better than a handshake. A handshake basically says "we just closed a business deal" and kills whatever spark was there. Maybe it's just me but I'd say if you like them, go for the hug, and if you really like them and the signs were there, lean in for the kiss. Worst case you get a cheek or a quick pull back and you laugh it off.
