This is very strange. Before travelling to New York with my friend Jean we stayed overnight at a hotel. When we left I was double checking that we hadn't left anything behind and that everything was in the right bag, passport, purse and the like. I was travelling with an empty rucksack because I always "acquire" stuff when I walk through an airport, like a newspaper, another book, some extra strong mints etc. So...I checked my rucksack to make sure I didn't have anything in there that could go into my hold luggage and pulled out these three items.
The locket I had never seen before, the boarding pass was for the last flight I had taken to New York with Davy to meet up with Jack & Betsy, the very same friends I was going to visit now , stopping off first in New York before flying on to Seattle where they live and the tissues I had bought when we were with them in Italy, their last visit to Europe. I have used this rucksack many, many times and never seen these items in it before. But the real mad thing is that my friend Jean used to have a business called Silver Locket.
I don't believe in "signs" and that sort of weirdness, but this made the hairs on the back of neck stand on end. Make of it what you will.
