Alike?

Many people say my brother and me look alike but i don't think so maybe it's because i seen him for 21 years already. However, while going through the photo yesterday, i realised we really look alike when we were young. Looking at a photo, i asked my Mum, who is the child in the photo?(thinking that the answer will be me). Then, the unexpected happen... "It's your brother"she answered. Huh? Not me!!! Eh... How come? i asked myself. I looked at the photo again and asked my mum again. Haha, her answer is still the same. Okay, we look alike but only when we were young. Haha...
