I dunno. There's some songs that come on that I still get that visceral goose bumps (like the first strains of "Pride and Joy" which is by now a really old song) so I don't think it's the age thing. It's just the things that always get you "right there" that may make it your favorite color (pink) or your favorite flower (calla lily), for example. Or favorite animal (horse). I'm sure my dad probably thought, Can't wait till she's out of her horse phase and enters her boy phase. Sure, I "discovered" boys but never outgrew my horse phase. I still act like a 5 year old seeing her first horse whenever I see one.
I'll hang up and wait for the comments.
