How do Angus and Mae make a living?

Angus and Mae sell things they make to people.
Mae sews and makes quilts and other handmade items. Winnie describes seeing rugs and quilts that are half completed. Angus does woodwork. Winnie says there are wood shavings, splinters, chips and sawdust in the living room. There are dolls, wooden soldiers, a model ship, wooden bowls, and utensils.
As Winnie explores the Tuck's home, she sees these things in their loft. They're scattered about and create a mess. She feels out of place because her home is usually orderly. She thinks that maybe it doesn't bother them because they have an unlimited amount of time to clean it up. However, Mae looks at the mess and seems to approve of it.
Mae and Angus's sons go away and work odd jobs from time to time but the brothers meet up every ten years and travel to be together with their parents. They also return home at other times, when they feel like it.

Angus and Mae earn money by making and selling things such as wooden toys and handmade quilts. It seems strange to say that they make a living when you consider that they are both immortal. However, being immortal means that the whole world is your oyster; you can go anywhere and do pretty much anything. Thus, it makes sense for Angus and Mae to turn their hands to something they can do just about anywhere in the world. Immortality has its drawbacks, though, the most serious of which is the potential for boredom. Angus often seems quite depressed, and it is largely due to the sheer boredom that immortality can bring. It is not surprising, then, that he and Mae make their own things, as the worst thing in the world would be for them to be tied down to any particular line of work. It is always so much more interesting and fulfilling to put your soul into what you do.
