If I had to give just one little tip to a first-timer, it would be this: Get a small sticky note and tape it to the microphone OR the PTT if it mounted on the wheel. In BOLD RED PEN, write just one word on it -- NO
Unlike 99.99% of what you have been taught about acknowledging every ATC transmission, do NOT say a single word UNLESS you are asked a direct question that REQUIRES an answer. no, No, NO talking unless you are on fire.
Even then, just give them coordinates so they can cover the smoking hole over.

It's great fun in the peanut gallery along 27 in the lawn chairs when some idiot starts talking to the controllers like it's old home week. We holler stuff like "shut UP you moron!" As we all laugh. The controllers always handle it very professionalky with only a hint that they're talking to a child who can't or won't read.
My funny was departing as the first IFR departure a couple years ago early in the morning Wednesday or Thursday I forget which. Forecast was for iffy VFR ceilings to start with the field probably closed to VFR traffic, and burning off and better to the West and co-owner and I needed to be back home if we could, so I played the slot time game on the iPad the night before and got one, and did all the correct stuff...
Taxiing out the ground controller says, "follow the flag men from there"...
You could tell we were by ourselves and he wasn't looking outside.
"Okay, they're not quite there yet but we're following the car that's about to drop him off in front of us. No problem, we're in no hurry."
Poor guy about kills himself diving out of the car and then... waving us past the car. LOL. Easy man. I'm not a jet and not burning hundreds of pounds an hour sitting here. Don't hurt yourself.
We played in the broken scud for about 20 miles and then blue skies all the way home. I felt bad for the radar controller... "Cessna 79M, Multiple targets, multiple altitudes all generally along your direction of flight... Maneuvering..."
The field had opened up VFR about two minutes after we departed (early by the forecast by at least an hour, maybe two) and the mad inbound rush was on...! I think that was the controllers way of saying, "Hell if I know if they're going to hit you... Hope you're looking outside!"
