Over 30 years ago when my sister was fatally injured in a road accident at the end of March. I was coninved that the last time I had seen her was the previous Christmas. We had been in touch by phone, but not met up since then. We had been in contact quite a bit because we had been organising weekend visits to a disabled aunt whose husband was in hospitaal
At the time DH was working in Japan and, in a time before email, I had been writing him letters that went out with his company's courier. About 10 years after my DS's death, I was tidying a drawer when I found all the letters I had written, which had been kept for some reason.
Re reading them I came across a reference to my sister coming down to my aunt's at the same time as I was there. It was brief overnight visit on her journey somewhere else. This was only 2 weeks before her death, yet the memory disappeared almost instantly, leaving me convinced i hadn't seen her since Christmas.
Since then I have been able to retrieve the odd partial memory of the event. - of her arriving quite late, of us standing in the bedroom we shared, talking, of the weather being very cold, but little else.
