Has anyone ever met siblings who look identical despite not being twins? Today I went to a colleague's house to drop something off and met her two DDs aged 13 and nearly 17. If she hadn't told me otherwise I would have sworn blind they were identical twins, even with the age gap, to me they looked completely identical except for hairstyle and clothes. It wasn't just me as she told me they're constantly getting mistaken for twins. It was really bizarre! I didn't even know that was possible. Obviously siblings often look alike but I've never come across it to that extent.
