I am attending a funeral on Thursday. I have never been to one before and had an odd childhood where I wasn't really taught a lot of social conventions so I'm feeling quite stressed about it. I won't really know anyone there, should I try and talk to people or just keep to myself? Its my friends brother who has died who I only met a few times but I want to be there to support my friend. Should I take flowers? What kind? Are strappy sandles ok to wear. I have a long black dress but it has thin straps, should I cover my shoulders? Also how long do devices normally last? Thanks for any help you can give.
