What would you say to a neighbor who unexpectidley lost their spouse?

She is less than a friend but more than a neighbor. She has a 14 year old daughter as well and was very close to her dad. They both there during this unexpected loss of their husband/father. We just don't know what to say or do for them. Please help. What would you say to a neighbor who unexpectidley lost their spouse?
first i think you should give them time to cool off, i think they don't want to talk about it so soon and they want to be left alone. what i did for my neighbor was i bought a really nice card and wrote how sorry i was and that if there was anything at all could do for them i was there. then i put that card tucked under their doormat so when they got home they got it. after a certain time we talked about it and he said thank you for the card.What would you say to a neighbor who unexpectidley lost their spouse?
