1) thank those present for coming to say goodbye (which seems stupid, but everyone is waiting for it and you have to say it) 2) some personal memory, the more specific, the better (fairy tales, holidays, favorite food, or best what you are 3) you turn to the coffin and say that you will remember the grandmother and tell your children about it and bow down, let it really be just a few sentences, at most ten (!) I mean it ... and no general words like "kind heart" and "always advised", you get involved and no one will believe you - just choose one or two events, even if they are more foolish and he will understand each of them mainly word for word write and learn it word by word, she will overwhelm you on the spot, there is no point in resisting, so it just is and you have to be able to say it completely automatically - print the paper in capital letters and take it with you and absolutely don't be ashamed to read it
