We're just in from chez Marie-Eve and Isaac. I can highly recommend befriending interesting people in the post office. Especially if they are Quebecers who like to cook. But don't call them French Canadians. That would appear to be a bit of a sore point. More similiarities with us Frozen North folk than I might have imagined!
As a general rule I can highly recommend hospitality in whatever form as a sign of the Kingdom. When you're a sort of worker cum sort of stay aroundish mum cum former very involved in stuff person, it's a nice way of still feeling connected. Unlike texting, which we have all decided tonight to be too impersonal. But then that could be the gluttony talking. You don't get a four course meal in a text!
