I am sorry for your loss. 
My family also does 'nothing' after a death. Thats how I grew up. My DH's family goes all out~ 3 days, DAYS ... of viewing, pot luck meals each day~looong line of cars...
When my Dad died, the in-laws were very vocal in their disapproval of how we did things. It really was none of their business. When MIL died a few months later, it was a full 3 day affair. I bit my tongue and was there every minute for my DH.
After it all was said and done, my DH told me he much preferred how we handled things with my Dad. He's told his family when he goes, it will be quietly and not to give me grief. I'm not going to hold my breath.
