You are so sweet to be there for her. Do you remember any cheerful stories that your friend told you about her daughter? That would be nice to bring up. Ask her how she's feeling, and what she would think her daughter would want her to be doing on this anniversary. Say a prayer together, hold hands, keep it soothing and calm. Think of it this way, it can be a really really sad day, or a comforting day. My mum passed in 2006 and not a year goes by that I don't honour her on that day. Always with her favourite yellow roses placed on my dining room table -- those were my mom's fav's. I also light a candle and just sit back and reflect - it's never easy.
Wishing you peace tomorrow, for your friend, her daughter, and Caylee Marie Anthony.
Thank you Mel,
She has shared special stories with me and I plan to bring them up. Just a sad sad weed all around.
