history: I found an old necklace my grandmother gave me for a birthday when I was very young recently. It brought back a lot of memories! I recently dug up a necklace my grandmother gave me when I was young for a birthday. I hadn't seen it in years. Oh my.. that must have been very sad. I can't even imagine how you must have felt. 
current: Yeah, she passed more than five years ago and I had forgotten all about it. It brought back so many memories though!
next: I'm so sorry.! But I'm really glad you've got those pleasant memories and the memento to hold on to so you can remember her fondly.
