One thing Caroline said to me once was ‘hate is heavy, let it go’ and it changed my outlook on a lot of things. I don’t know who they are and don’t wish to, but don’t let people sicken you, just block them out of your life and remember Caroline for who she was, and any memories you may have had with her. Personally I know her family and friends will be grateful for any words of comfort given to them by anyone who knew her and anyone who only knew her from TV. Like I say, no one will know every single person who was in her life, but they’ll know who she talked to them about, who they met when she was alive etc.
Sam does seem like a sweet person from what I know of her, albeit the things related to the fall out were not so sweet. Mollie and Lou were not a good influence, but were good friends if you wanted a party or holiday.
