Retired Generals never get over the fact that the minute they retire everyone who had to kiss their ass can now ignore or hate them.
Years ago a four-star told me this story:
After he retired he saw a convoy going too fast. He pulled up next to the lead vehicle and made a motion to slow down. The driver looked at him and then flipped him “the bird”. He said he realized at that moment he was no longer a four-star general.
