Naive I guess even though I am a little old for naivety.
Scott, I laughed when I read this. Maybe it's because we learn to play as kids but musos seem prone to regression to youthful and childish behaviour (Keith Richards, anyone?). It's a bit like when you inwardly kick yourself yourself for being childishly petulant after your mother forgets that you're grown up and tells you what to wear - lol
When I was playing keys we auditioned for drummers and invited a guy back for a second hearing. He was really sloppy second time around and our singer was visibly displeased. So we talked about it and I sent him the "Dear John" email. This responsible 50 year-old family man with a business wrote back, saying "F OFF!".
At first I was in shock but, then I just cracked up. It was pure regression. I wrote back saying, "Hey, that's pretty rock'n'roll of you" (with added smiley) and he got back again with an apology and it was fine; he returned to his adult self.
When I first started playing again after a long layoff, once I got my chops back I started doing all these stupid showoffy things in songs that only added clutter to the music. Oops - kidult alert!
The moral of the story is, if we are aware of how easy it is to fall back into our youthful musical personas, then we are better placed to be the grown ups that we (hopefully) are. Whatever, you seemed to enjoy your brief time with the band so, while they may have used you, you didn't walk away empty-handed. Maybe you weren't
used so much as engaging in a brief symbiotic relationship? *grin*
