Is OTHER wrong in the post ? POST : I am 13. I have braces. We were getting our school photos taken and my mom told me NOT to smile with my mouth open during the photo so my braces don't show. I said okay but was unsure of how to look good in the photo with my mouth closed. (I'm not good at smiling with my mouth closed.)

When it was my turn to get my photo taken, the camera man told me to smile. I am not good at speaking up, so I just sat there uncomfortably and moderately smiled, or tried to, with my mouth closed. The camera guy again said, "Come on, give me a smile!" I gave in and gave a nice, big smile. He was very friendly and not at all condescending. 

Later, when my mom saw the photo she got angry with me and said "I TOLD you not to smile with your mouth open." I told her that the camera man told me to smile so that's why I did. I then told her that she was being shallow for being so upset about my braces showing and caring so much about what other people will think when they see this picture. (She cares a LOT about how her kids look to other people, especially relatives.) Yes braces are unattractive, but they're part of who I am for the time being, they're fixing my teeth, so why hide them??

She again got angry at me for calling her shallow (disrespectful) and that I should have listened to her and not the camera man. 

AITA?
