My neighbor uses his snow blower to clear my driveway and the sidewalks. By city ordinance the sidewalks must be cleared within 24 hours of a snowfall. And I take him and his family something that I have cooked; they both work and it is a blended family of four children, so I take soups in quantity or a dish that will feed six.
My church has a group of volunteers called " Helping Hands." If someone needs help or transporation or food, they send an email giving the type of help needed in to the coordinator, she sends a request out to those who can provide the requested type of help, and usually within an hour or two, the requestor has a reply of someone who is volunteering to provide the needed type of help. I've used it for moving furniture, for meals when I've been ill, for transportation after knee surgery when I've been told I'm not to drive. In return I'm on the list to provide transportation for those who mustn't drive. Through this service I've met individuals I would not have met otherwise.
