So there are two photos of me when I was 13. I compared the photos to a picture of my mom when she was in her 20's or 30's. We looked so much alike. Then when I was still 13 I did a photo shoot and I compared the photos to my mom. We didn't even look related. We didn't look alike when we were the same age either. This doesn't make any sense to me. How can a photo of when I was 13 look almost exactly like her when she was in her 20's or 30's but the ones in the photoshoot look nothing like her?
