Fortunately my son's friend who shares an office with him lives in the next complex and next drive. I pretended I had turned in the wrong driveway and fortunately he was home so I had him get in the car with me and drove him to my son's right past those people so my son could drive him back! :) Talk about the hair on the back of my neck standing up -- all I could think of was to get out of there ASAP.
I was hoping you didn't go alone and was thinking along the lines that you need to have a student in the car with you as a cover.
Smart thinking (picking up your son's friend).
