I was thinking that maybe this happened so you could spend some time thinking about your nana....she's with you and wanted to connect with you for some reason...maybe a meditation while you try to fix the necklaces so that you can figure out what she is trying to tell you? I feel like she is just trying to get your attention, and now that she has it, wants you to take the time to reflect on the connection between her and your baby girl....
don't feel sad, she wants you to know that you are still with her, and she wants to connect with your daughter.....timing is everything.
P.S. Congratulations on your co- hosting gig!
