I've always called these "triggers." Everyone gets them once in awhile and usually one is caught off guard completely. I don't think it will ever be any different. As we age, more happens, more people leave us and on and on. We tend to widen our memory file more and more. We miss more people, pets and places. We become huge memory banks and I believe it tenderizes our hearts more with each loss....therefore, all the more triggers. yeah, count me in as a sap, too, if that's what I am. There are certain things that if I see, hear or smell take me back to precious memories of someone or something, particularly music that my big bro and I shared, or flowers that Mom loved or a place that I devoted my life with my ex-husband. All of it stings but can be beautiful if looked at in the right way.
