I'm in a difficult dilemma and would like some advice before I decide what to do. My niece died over 10 years ago and I take flowers to her grave twice a year. My sister hardly ever goes and because of how bad she's been since her baby died, we can't talk to her about it, she just shuts us down. I don't want to upset my sister but the grave is very messy, the cross has rotted so much and it breaks my heart to see it like that. I want to buy another cross and tidy the grave up but do I talk to my sister and have her shut me down or shall I just do it behind her back? I want to do it for my niece but don't know what to do for the best.
