I am not a teacher nor a biological parent. I do have two baby sisters that were born in my teen years that I have literally been a surrogate parent to them for most of my life. Also, I have an almost 11 year old stepdaughter.

My first reaction to your question is that the teacher out with a few of his female high school students may be inappropriate but a stupid choice for sure. In todays world if I were a teacher and wanted to take my favorite students to dinner, I would most certainly have another adult with me. (Most likely I would take an adult woman if all my students were young women.)

I do not think you are over reacting. I tend to agree with Jagg and talk to the teacher directly first. If he is shady he will then know someone is onto him. If not, "No harm, no foul." In the least I think he would rethink socializing with students that is not an official function of the school.
