After September 11, 2001 the country had a bit of an epiphany and caring about each other was paramount.
Things are different now. The incoming administration is violent and untrustworthy. That trickle’s down to effect society. We are entering a time as Americans where people carrying weapons think nothing of expressing aggression. There is permission for that behavior by incoming authorities in Washington, DC. with the enforcement of “the steal,” and releases from prison of insurgents with proven ideology of violence.
Personal safety is being redefined. Caution is returning as a preferred social directive. There is no such thing as casual friends anymore.
It is a shame this is occurring to the USA, but, it is.
