Huh??

So today I was doing stuff that I do when I'm bored. Well, some of you may or may not know that I have heterochromia (difficult word to say that I have 2 different eyecolors) So my left eye is just blue, and my right one is also blue but has some brown in it. And I looked through some pics, and I noticed I didn't have this when I was little! It came as I got older. Now I think that's a little weird..

See, when I was little, my eyes were both blue ,no brown to see

Now, this is a picture of my eye now

See?? Isn't that weird? At least I think it is...
