For bros: No purple suits, no white suits. Don't care if it's all you can afford.
No noisy cars.
No side jobs at home (my husband was a mechanic), because you'll be distracted.
(We drove a 69 El Camino to the meetings that we had restored, it had Flowmasters and was not 'noisy' - it was cool. We couldn't afford a newer car because my husband had to stop doing side jobs. There's no winning when the rules start flying.)
I hate them. Hohos.
