Conversations From A Long Marriage nestles happily in its 6.30pm comedy slot. It's cosy and gentle and - for me - slightly phoned in by these two great actors. The stories and jokes often revolve around one of them desiring a bit more attention from the other: we've had Joanna wanting Roger to be more physically affectionate, like a lusty couple they know, and Roger being grumpy about Joanna working with a dynamic younger man. Surely most long-term couples are relaxed about such things, while being far spikier about others? Perhaps I'm wrong, and everyone else, apart from me and my husband, is in an exquisite Joanna & the Maestro-style relationship. Whatever, I will always have time for Lumley, who somehow manages to make everything in life, even ludicrous garden bridges, more absolutely fabulous (sorry). There are few people who can do that.
