I'm with you and your Gramma, gnu. Get while the getting's good.

When it's not, you might as well go help someone clear their lane and/or sidewalk. If you can't do heavy work, go out and chat with them anyway--they'll likely appreciate the visit and breather. Or put ice-melter on an absent neighbour's walkway & stairs. Or, my personal favourite, put on your cleats (I swear by Icers that I got at Lee Valley, worth every penny) and take some dogs--including a neighbour's--for a walk.

Anyway that's my version of throwing a few more veggies in the pot. Those bad weather days are positively the most social ones in my neighbourhood, when there's no choice but to slow down and spend a little time with each other.
