The family use their house as a status symbol and have decorated it in a way so as to reflect their wealth. We learn this from the 'few imposing but tasteless pictures' which will probably have been chosen because they were expensive, not because they were liked. These pictures also tell us that the Birlings are proud of their wealth and think themselves to be very important but lack the good taste which is present in those who are socially superior to them. The house is described as being 'substantial and comfortable and old-fashioned, but not cosy and homelike.' This setting suggests that the family are uncomfortable with each other and therefore suggests problems. They speak to each other in a fairly relaxed manner, despite the attempts from Mrs. Birling to enforce a more formal atmosphere by correcting her family whenever they make minor errors in table manners. The champagne shows that family are joined to celebrate. Gerald is a guest at the house and so the family are all well-behaved and pleasant to one another but there are several hints that this is for show and there are problems which are being ignored. Mrs. Birling treats Eric and Sheila as if they are two small children even though Sheila is engaged to Gerald and so is a young woman. This is shown when Sheila refers to Eric as 'squiffy' and Mrs. Birling scolds her by saying 'What and expression, Sheila! Really the things you girls pick up these days!' This also shows the difference between the generations; Sheila is younger and so does not act in the same way that her mother thinks women should act. It also suggests that she is reluctant to let her children grow up because once they reach a certain age they would move away and she would live with just her husband, a prospect that she seems unlikely to look forward to. Although the audience is unaware of any problems she and Birling may have, we are given a hint later when she tells Sheila that 'When you're married you'll realise that men with important work to do sometimes have to spend nearly all their time and energy on their business.
