DM and DF don't really do anything except read thrillers from the library, watch TV, and take the occasional trip out to an NT property or shopping centre. They don't eat out much except sandwiches from said NT cafes/shopping centres, they don't drink, they don't eat chocolates (well, DF would but DM moans about his weight), they don't go to the cinema or theatre (theatre token gifts from a few years ago still unused). We bought a basic Kindle tablet for them a couple of years ago but that's also unused apart from occasionally Skyping their granddaughter.
DM not very mobile, doesn't have any particular interests, doesn't express enthusiasm for any gifts received. Perfume, jewellery, scarves etc all get an "oh, that's nice" then shoved in drawer. DF more mobile, interested in old buses, trains and trucks, but I feel that we've exhausted the "book/DVD/calendar of old transport" route. Does anyone have any ideas apart from more variations on the 'steam train/Ian Rankin books' theme?
