Even though you don’t know her, go to the funeral anyway. She wouldn’t have invited you folks unless she wanted/needed you all to be there. Be discreet, but go up to her and introduce yourself and give her a card with your name, address and phone number and little note letting her know that she can call you anytime with a little list of suggestions for jobs or tasks that you and the other neighbors can help her with like mowing her lawn, getting her trashcans out, picking up some groceries while you’re at the store, helping her to organize her household or do some cleaning (she will most likely have to go through all of her husband’s things and may not be able to deal with it herself, and would be embarrassed to ask, but offer that idea in a discreet manner) You can say something like you’re really organized and energetic so if you need any help with getting “organized” she should get the picture. Either the day of the funeral or the next day, take a casserole and/or some cookies or a cake to her home. Let her know that if she wants some company either for lunch or coffee or just to go to the store with, you are available. Let her know that there are plenty of “husbands and men” in the neighborhood (that could also mean the women too, but this is more obvious) that can help her out with her car if she needs some help or with moving any heavy objects etc. You could also give her a short list of names, addresses and phone numbers of the 10 closest neighbors (but only the ones that you know might be willing to help her out). Then give her a week and then put another nice card or note in her mailbox and let her know that she can give you a call (people often forget about the bereaved right after the funeral) and let her know that you’d love for her to come to dinner when she’s feeling up for it. Even if you don’t hear back from her right away, or even in a week or a month. Send her another card just letting her know that you’re checking in and want to let her know that you’re still thinking about her and available for anything that she might need. Maybe send some flowers after about a month has passed, even if you gave her flowers in the first place, or better yet, a potted plant. And wait about 3 weeks to bring her another casserole. Just do everything that you can, to not intrude upon her privacy, but still let her know that you are indeed thinking about her and that you are available to assist her if she wants/needs help.
Other ideas for areas where she might need help: cleaning out the garage (especially if her husband had all sorts of tools, projects and other stuff out there) helping her with a garage sale down the line (she probably will need to do it, but that can be especially painful) look up some bereavement counseling in your area and keep them on hand (but don’t give them to her immediately and not until she either asks for them or shows signs of severe bereavement down the line, don’t force this info on her, but have it on hand) watering her yard or doing other heavy yard work like mowing, pruning, weeding, sweeping etc. A lot of times, the husband was responsible for those tasks, she may not know what to do or even be up to the task. Does she have any pets? If so, ask if she would like you to walk them or if she needs help cleaning out the litter pan or humping bags of litter or pet food into the house. If you find out that she will have relatives coming into town, ask her if she needs any help getting her guest room or couch set up (let her know that you have extra sheets, blankets and towels) plus extra folding chairs or even a camping cot if she needs them. If she seems to be overwhelmed about keeping track of who helped her with whatever, ask her if she wants you to help her keep a log of who gave what casserole or flowers or whatever and if she needs some help addressing (or purchasing) thank you notes and stamps and taking the stuff to the post office. Maybe you can make up a little list that you will keep (until she needs or asks for your help) of all the people, companies or organizations that need to be informed of her husband’s death. Sometimes bereaved people don’t even think about all of the people they need to contact, like the bank, the car repair place, or any other places of business that the husband used to regularly do business with (magazine subscriptions, the local gym membership etc).
Thanks for being a good person and being willing to help out. There should be more people like you : )
