You probably think the word I had in mind was gay, right?

having or showing a merry, lively mood:
gay spirits; gay music.

bright or showy:
gay colors; gay ornaments.

Wrong-oh. The definition above is from dictionary dot com and the word I had in mind was frivolous. I was making a grievance presentation in a meeting and I unraveled. I started the show by explaining what a grievance was and made it clear that it was never intended to be a personal affront or attack on an individual, a service, or the agency as a whole. At some point in my declaration I gave pause, sighed, and lamented that I was troubled and puzzled by a particular supervisor whose very raison d'être is to attack others and write them up for bruising her ego.
I called her charges frivolous and I must have used the term quite a bit because the chief asked me about it. I accused this person of throwing her weight around (yes, she is morbidly obese) and of having an unquenchable and insatiable need to report others for the most trifle and trivial infractions; they didn't jump at my command.
So I called her mean. "She's mean, mean, mean!" And I had submitted emails that she had sent to the worker bees telling them to write reports of contact against others.

Calling another person 'self-indulgent' can be a bit harsh. It describes a person who follows his/her/its
own desires, passions, whims, etc., without restraint. We're talking ice-cream in the freezer and whipped cream on the fridge door. I never think of myself that way. I'm the one who recycles, the one who wraps foods in wax paper or cellophane. I walk or take the stairs. It's not part of my lifestyle and I don't ask anyone to snitch or rat out another.
I feel so much better!
