A
My sister was sick for a long time before they found out what was the matter with her. She had so many tests , and no answers came, till one day we heard the words we were dreading " Your sister has a rare blood vessel cancer, hopefully we can remove it, but we have only seen 5 cases ,and don't even know if she will survive"
My wedding day was in November, and the family spent most of their time going to the hospital ,so I was on my own with all the arrangements. Not that I minded, we were just waiting to find out what was going to become of my sister.
Finally the surgeons decided amputation was the answer after extensive radiation therapy to shrink the tumour. She was tired and lethargic, and tried hard to put on a brave face, but the fear showed in her eyes.
Fortunately, when the surgery came, the doctors found they could remove the tumour without amputation, but at a great cost. The whole leg muscle was removed , and became infected, and it took many months for my sister to become well enough to leave the hospital, but was unable to stand, let alone walk.
The day of our wedding came around, and still my sister remained unwell, and was not coming to the wedding. I felt sad inside at the thought of it, but she had survived the ordeal ,and that was enough for now.
It was the only dark spot on the happiest day of my life.
As the wedding car pulled up, I saw the family moving around the church ,and felt a slight pang....Jayne was not going to be here to share all this... I stepped out of the wedding car, and rearranged my gown and dress... the church started the bridal march... ...and as in a dream, there was my sister, standing up, supported by two crutches, smiling. I think I am the only bride who stopped in the middle of the bridal march to walk over and kiss my sister on the cheek. It cost my sister so much pain to be there ,to stand and even walk a little. She could not manage it for long, but she did it for me, even when her own future looked uncertain. In my bridal book, there is a page for gifts... and next to my sister’s name is the entry..."Jaynes gift...my sister walked on my wedding day"
And her gift is the one we remember most...
