Mrs Broadbent’s new 'granny' flat needs decorating before her mother arrives, but the decorators have not turned up. Ever helpful, Bob rashly offers to do it for her, even though he's never done any wallpapering. Wendy has been decorating his kitchen, so Bob asks if he can borrow her brushes etc. Wendy is not sure that it's such a great idea, but Bob is convinced putting up wallpaper can't be that difficult...until he starts work that is! Wendy goes to see how he's getting on and finds a terrible mess.  Tactfully, she suggests he take a lunch break, whilst she 'tidies the place up'. As soon as the relieved Bob has gone, Wendy gets to work. On his way back from lunch Bob bumps into Mrs B, eager to know how things are going. Assuming the flat is as he left it, he tries to stop her entering. Undeterred, Mrs. B opens the door - and thanks Bob profusely for doing a wonderful job! Surprised, Bob follows and discovers Wendy standing in a beautifully wallpapered flat. He tells Mrs. B her thanks are due to Wendy, not him. Mrs. B congratulates the bashful twosome on being a talented pair.
