sentimental: 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.

Yeah, she passed more than five years ago and I had forgotten all about it. It brought back so many memories though!

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.
