1. You’ve stood for the national anthem at a movie theater.
As well as during that awkward moment when you stand up just to find off-base theaters don’t play it. (I recommend playing it off as a quick stretch.)
2. You stop for Retreat and Evening Colors.
Remember cruising around a military base around 4:00-5:00 pm and everything grinding to a complete halt as “Retreat” bugled over the loudspeakers? Even cars stopped! Don’t forget Reveille at 7:30 am and Taps at around 9:00 pm.
