My friends grandfather died Sunday or Monday?

Sorry but it was one of those days. Well she took it pretty well and the funeral was today. Well her grandmother is dropping her off school tomorrow which I think is to early since she just lost her husband so she should be in bed but maybe she is strong like her granddaughter. Well I never met her grandma just wave to her when she pulls up. Well tomorrow I am going to talk to her when Kenzie gets dropped off but I want to know what to say to her. I dont want to say im sorry for your loss because thats so well boring and worn out so what else can I say?
