As was usual for Mum , she did her best to 'prettify' her home even if it was in a CPR Section house . By the time our family had moved to Larchwood , the company had relaxed the rules for interior decoration . Now , a section family could paint the interior walls whatever colour desired...but the CPR would only provide free paint in their official colours . The exterior must have the look of CPR property ...no exceptions . Of course , since section men were the lowliest of employees , the 'working poor' class , most did not exercise this great freedom granted by the company . They couldn't afford it .
