A friend I haven't seen for 5 years has just lost her teenage son in the most tragic of circumstances. She will no doubt be in absolute bits ATM. We fell out, not in a major way, but our last conversation ended with me hanging up on her. Our DDs (both 18 now) also fell out. I knew the boy more when he was a toddler/young child and thought alot of him but hadn't really seen him for around 7 years.
So what's appropriate? She's posted about it on FB but we're not FB friends. Do I send her a message or post a sympathy card? I know when I had bereavements I really appreciated any cards or messages from anyone.
