I am a rising sophomore in college and I just finished a summer internship at a literacy camp for 6th-9th graders. I had a good time with the kids, and things went well over all. I definitely learned a lot about teaching and leadership. However, I look very young. I'm only about 5'1 and I have a baby face. Meeting the parents was awful because every time they visited, I would get comments like "I thought you were one of the kids!" Yesterday, a parent asked how old I was, and I said I was 18. She looked shocked and said "I thought you were 12!" I was mortified, so I just walked away. However, this hasn't really been a problem with the kids since they knew who I was. Does anyone have advice on how to respond to parents like this?
