Oh ZS! I am devastated for your sister, YOU, and your family – I am so sorry!
When we lost our Molly (dog) a few years ago now, I couldn’t think straight – the grief overwhelmed me. But I knew I had to do something to mark his life on this earth and through my tears (sob’s actually) I ordered a plaque to attach to the rock/boulder we placed on his grave in the garden. Embarrassingly, I called him again that afternoon thinking I wouldn’t cry and he could understand me (didn’t happen!) to change what I wanted written to – 15 years in my arms, forever in my heart. It just came to me!
I think, once you can think straight…. there is so much you can do – just choose something that you think is special to your sister, you know her best. I love all the idea’s that have been suggested and mine is only one of many. You know, I would have loved someone to have done that for me. I just took it all upon myself – it never occurred to me that someone (like you) would do that for another over a loss. Your truly wonderful ZS!
