I wanted to buy Sara a present; that was made me understand what had really changed. It was a week before our fourth anniversary and a month before we were still due to marry. I was in town alone and I decided that I would buy her something for our anniversary. I knew that no gift was going to make it better, but I wanted to signify to her that I was thinking of her; thinking of her more than I thought she knew.

I wandered around her favourite stores, looking for something that would make her smile, that would let her know that I had thought about what she liked, who she was and then I had found the perfect gift. That was the problem though; I was looking, and she could not do that anymore. After about an hour it dawned on me, and crazy as it may sound, I think it was then that I really understood for the first time that she was blind. I could not buy her a beautiful painting or exquisite jewellery, things that would once have captivated her with the way they looked. Now that was only cruel, not thoughtful.
