I have younger sisters that are identical twins. (Borderline pedo/jailbait young so no asking for pics.)
They've had very different personalities from day 1. They had their own ideas about favorite colors; we planned all the pastels for the older one and bold reds and blues for the younger one but they preferred the exact opposite as toddlers. They've never played switch on anyone and get slightly annoyed when people mix them up. They did have a few "twin" words when they were little, like names for each other and blankets, but not especially more than any other babies. No complicated twin language though, and it ended as soon as they learned to talk.
I can tell them apart by look and voice though it's hard if they're not facing me, and it's gotten harder as they've gotten older; I call them both "Sugar" or "Angel" and either will answer to that so it saves me effort.

They know who is older, by two minutes, and it doesn't seem to matter to them much. They boss each other and fight like normal siblings. They never dress the same although they will share clothes. They play the same sports and have mostly the same group of friends.
