I have a student who recently got her tongue pierced. (She's also pregnant by a boy who's in 9th grade for the 3rd or 4th time, but that's another story....)
She was showing off her pierced tongue for the other kids the other day, and said something to me. I asked her if she'd be talking like a 3-year-old from now on, or if that would go away?
Haven't heard anything else about the tongue-piercing since.
Your story makes me believe that your student has a solid history of making unwise decisions.
