One of my oldest school friend's dad has recently died (in his late 70s, after being very unwell for some time). I'm not sure whether it would be appropriate to go to the funeral, as although I obviously saw him fairly regularly when I was growing up, I haven't seen him or my friend's mum for many many years now. But I am in regular touch with my very good friend and am obviously sad for her that her dad has died.
The funeral is likely to be about an hour away from where I live, so not hugely difficult to get to (but not just round the corner). I could fairly easily take a day of annual leave.
Is it weird to go to the funeral? I don't want my friend or mum to think it's inappropriate since I didn't know her dad well and haven't seen him for a long time. Or do people go to this kind of funeral on the basis that you are showing support for the relative who you know?
