This seems like a simple concept, but apparently it needs to be pointed out over and over again: when you're over 18 and you have sexual contact with someone under 18, it's illegal, and people are eventually going to find out about it.

Especially in high school.

For the second time this week a local teacher has been arrested on suspicion of sexual conduct with a minor. This time, 23-year-old Flowing Wells district teacher Christina Marie Carbone is accused of having sexual contact with a 16-year-old boy. The student, who attends a TUSD school — not being your own student doesn't make it any less illegal — met Carbone at a social event in March, according to the Pima County Sheriff's Department.

This comes on the heels of the arrest earlier this week of Melissa Ann Dalton, 33, an Ironwood Ridge HS art teacher, for allegedly getting it on with both a 16-year-old boy and a 15-year-old boy in her car and her classroom.

Yes, we all know that teenage boys can be dreamy. Just wait until they're of age. Oh, and after they've graduated, or is that no longer make it exciting?
