Jo -
You're now hearing life in mono instead of stereo sound. It is very odd, to say the least.
I've "trained" my family to not just say "I'm in here" when I ask where they are because I can't tell where "here" is - they have to say "I'm in the kitchen" or something specific. I've been known to walk around in circles throughout the house to find my kids. I could have sworn I heard them in the living room, but darn it, they're not in there!
It was frustrating at first, and I'm convinced my kids have used this situation to their advantage at times, but eventually you just learn that it's all a part of the fun they call single side deafness!
And speaking of using it to your advantage, I've found that having my 7 year old, who talks incessantly, walk on my deaf side, while I just nod my head and say "mmmhmmm" every now and then, can really be helpful!
Do I really need to know what every kid in her class had for lunch that day?
So, in answer to your question.... it is quite normal to be abnormal.
