That gun is a relic.
Similar deal to you, pretty much my parents' entire house and all its contents has a lot of sentimental value, there's a lot of memories in there. Sibling dearest is inheriting it and it's left to the kids after that (and who knows what will happen at that stage it's a very long way off).
I have some jewellery that I got given that has sentimental value despite me being not able to wear it (okay I can technically wear it but I don't because jewellery tends to just shatter on me). My daughter is wearing one of the pieces that my mum got for me and it looks really nice on her, and she doesn't have the jewellery destroying problem that I do XD
A relic indeed, and every time I fire it I wonder if that'll be the time it explodes and takes my head off.
Do you find the items sort of link you to those that owned/used them before you? That's how I feel, and I like the feeling as it give me a sense of belonging.
At least we can say you died doing what you loved?
please don't get exploded by the relic XD
There's definitely a bit of that feeling with the family home, think the kids or their kids would have to sell it off if it leaves the family once we're dead as you'd pretty much have to pry it out of mine and sibling dearest's cold dead hands XD (and given the age gap I had better die before she does).
