I agree on prepared food. If you met her in Hebrew school I would guess there will be a funeral in the next two days - and that means a lot of people will be coming by. One of the biggest things someone did for us when my grandma passed away was get trays of prepared food for us so there was something for visitors to eat, because none of us would have thought much about that with everything going on.
Of course, try not to do what they did and buy ham and cheese sandwiches if there will be many folks who may keep kosher around...
The pews never miss a sermon but that doesn't get them one step closer to Heaven.
But at least the pews never attend yoga!
