True enough that no one knows what might or might not work in any given situation. The cherry picking by some is revealing in and of itself. Each of us brings our own experiences which color what words mean. Being nice can encompass the most selfless actions to the smallest gesture.
Examples:
Once I pushed K. in his chair at a breakneck *not really but fast is relative* speed through the corridors of a local hospital dodging in and out making him laugh uproiously….at the end of the day more than one person came up to me,making a positive comment . One person said that changed the way they would look at people like my son.
I was a grounds person at another hospital who used to sing, quietly,as I worked ~ again people would come up and comment positively. One watched while they waited for news about a loved ones surgery. I,unknowingly, simply gave them a pleasant divergence as they anxiously waited.
How any action is seem,taken in by another…You just never know,do you?
Simply put: I would rather go about doing and encouraging “nice” by any measure.
