Penelope has a special talent.

Whenever she sees a picture of herself and Zahra, she always (really, always) identifies Zahra correctly.

Even if she hasn't seen the picture before, she'll point right at Zahra and say "baba" (zahra). Even if the picture if from nearly two years ago, when they were itty bitty babies. How does she do this? Any ideas, fellow twin-parents?

Perhaps it's because she's spent every day of her waking life with her sister, so she's pretty darn sure what she looks like.

Every day these girls surprise me with how much they know and understand about one another.
