Well Thats ok,,If you're unable to attend send the family flowers that they know you remember him.
You send fruit baskets or food to Jewish families , we got no flowers when my dad dies . We got a lot of food b/c we sat Shiva for seven days , my mom did . People brought her all kind of food. I went to work , I was told to take off as the 7 days if I wanted to. Mom did not have cook any food is she did not feel like it .
