What’s really funny to me is that when you’re eleven, everyone over the age of sixteen kind of just looks older than you so Harry probably didn’t notice just how young James and Lily were the first time he saw them in the Mirror of Erised. It probably didn’t hit him until a few years later when he was looking at old photographs or even in the forest when they were right there in front of him and he was like “…wait a mINUTE”
