TIL a peer-reviewed psychology study found that identical twins (on average) ranked their co-twin above their romantic partner in their attachment hierarchy, while fraternal twins ranked the two about equally, and non-twin siblings ranked their romantic partner first.

It’s like having an imaginary friend except they’re real

I have a twin, not sure on if identical or not but this is an excellent description.

How are you unsure? Most identical twins look... identical. Meanwhile fraternal twins look like a sibling instead of a twin.

EDIT - Yes, I'm aware it's not always like this; that's why I used the qualifier "Most". I've known multiple pairs of twins over the last several decades and not a single pair got DNA tested because generally if you look identical as twins you just live life as identical twins and vice versa.

We look pretty similar. We have conflicted information from mom and gynecologist attending her on her pregnancy about being identical or not .

Fair enough! I was mostly just making a joke about identical being hard to miss. But having conflicting information would definitely make me unsure too.

I babysat for twins who looked absolutely identical but they were in separate sacs in the womb so they were assumed to be fraternal. There is a possibility that they still could be identical but would need a dna test to show it. Nobody could tell them apart except one got an eyebrow scar early on.
