The most obvious one is that he is now cross-eyed. That you can spot from a mile away. When he smiles, it is with the same bright, one-dimple smile he always had. But his eyes are different, and it throws me off sometimes when I'm not expecting it. It's only when he laughs, that it's really hard to see any differences from before. I see this in his attitude as well. He is the same sweet, loving boy he has always been. But then there are times when I can see that he is different, somehow...scared but stronger, and more aware of his surroundings, if that is possible.
Watching him is kind of like watching identical twins: they look exactly the same until you study them, and then they begin to look different. Pretty soon, you can tell them apart, but you're not really sure why.
The same, but different...The son I know, and the son I am getting to know...the concept is strange, but interesting to see. Mason is different, changed, and somehow still the same.
Spot the differences.
