I took a series of photographs of the twins just recently. This one
was almost consigned to the waste bin. Then I had a thought.
Perhaps this is what mystery looks like, when it surrounds certain aspects of behaviour.
At 18 months old, they are into everything. They play together and they play independently, finding new and interesting applications for the contents of their toy box. They share their snacks and pass each other's drinks. They squabble over a single item yet, openly offer the spare, where there are two.
If one gets upset, the other cries too. When either of them lands with a bump, the other is there with a look of concern and a reassuring stroke of the hair.
Most curious of all is 'twin talk' or, cryptophasia. More often than not, they'll communicate with glances or hand gestures. At odd times, you can feel like an outsider, as they actually talk to each other in their own language. It is totally exclusive and, although it sounds a bit like gobbledegook, it's mutually understood by them.
I've heard all kinds of stories about identical twins. Among the most interesting was one told to me by a friend and former colleague. When she was at university, one of her lecturers was an identical twin. He had a very bad stammer, which was sometimes hard to control. His twin brother was also a lecturer in another university. During the time my friend was being taught by the brother with the stammer, his twin died. Almost simultaneously, her lecturer lost the stammer he'd had since childhood. A mystery, don't you think?
