People who know me know I'm pretty keen on personal accountability -- for myself, and for other people.
Those same folks know I don't have to know you to hold you accountable.
I'll be professional, I'll be constructive, but if you are doing something blatantly untoward in public, it's totally possible I'll chat with you about it. Society's arguably in a bit of a nosedive, and I'd argue societal character disorder is at least in part at play.
My kids know this, too. Sometimes, that bites me.
Last night, I was helping my 4-year-old with something she really should be able to do on her own.
I stopped what I was doing, briefly helped her, then went back to what I was doing.
"You didn't do it right."
"Look, Sweetie, it's not my job to do this for you."
"Yeah, but it is your job to do the part you said you'd help me with right!"
She's totally right.
Note to self: Avoid transparent half-assery.
