Speaking of regret...
We were at Blizzard Beach in March waiting in line for the Double Dipper and there was a group of about 4 girls in front of us. They looked to be upper high school or early college aged. Cute, slim, bikinis, fun little accessory jewelry. And, then one girl turned around and on her beautiful flat stomach was tattooed in large, ornate swirly-script letters, extending from hip bone over to belly button (this thing took up most of the skin on the one side of her stomach) was the phrase: Je ne regrette
Talk about putting your foot in your mouth. I am of the opinion that if you tattoo "I never regret" across the expanse of your young, taut stomach at the age of 18, that, yes, some regret will most definitely creep in at some point.
