Lynne is in the shower. She thinks to herself that she's heard that Melissa has employed a new gardener. Due to this, Melissa has hardly spent any time in the garden, but neither has her gardener because he is constantly in the house with Melissa.
Lynne does a lot of her thinking in the shower. She enjoys the solitude and the warm water stimulates her brain. On this occasion she is thinking about Melissa's new gardener. Has Melissa employed this gardener because she now simply does not have the time to work on her garden or because the old gardener has had to leave for some reason? He may have got a better job, moved to a different area or perhaps died. He may have quit because Melissa never left him alone.
Melissa and the gardener look like they are just outside a bedroom. This implies that they are having sexual relations. Melissa is wearing a revealing top which implies that she is trying to seduce the gardener. The gardener looks to be pulling away from Melissa and making a face that says “What are you doing woman?” He's got rhodedendrons to cut back. His hair looks slightly ruffled. This may be due to working outside but it could be that this latest tryst has just been completed. He has quickly put his dungarees back on and wants to make a quick exit.
Lynne, although thinking about Melissa and gardener initially, decides to shout the last part of her thought. It is not uncommon for Lynne to do this but at least on this occasion no one is around to hear her. Is this a form of tourette's that she has where she has to blurt out the last part of any thought? It may be the reason why she says so many bad jokes aloud because if she thought them people would be constantly hearing her punchlines. Immediately after this, George shouts up the stairs “Who are you talking to dear?” and Lynne feels very embarrassed.
