One of my closest friend's Dad has just died (for those of you who may remember, she was walking for him, and I was walking for my stepdad in a brain cancer walk in May). She just texted me the times for the wake and the mass. I'd like to attend both - here are my questions: 1) Is it normal for me (close friend of daughter, met him many times) to attend the funeral mass, too, not just the wake? I don't know how formal a funeral mass is, ie, whether it's really only for family. 2) Anything I should know about Catholic wakes/mass? I've only been to a Jewish and a non-denominational funeral service before, I don't know what I'm in for.
