What importance event in CHAPTER 6 in the railway children?

The children asked to have the cakes on Thursday. They wanted to make a birthday tea for Perks. Peter wanted to ask everybody in the village to help them give Perks a nice birthday. Not everyone was kind. Old Mrs Ransome said no one remembered her birthday so she did not want to help but many gave them all kinds of things to Perks. The next day, Bobbie and Phyllis gave Mrs. Ransome roses and a handkerchief for her birthday. On Thursday, the children went around to collect presents the people had promised. At three o'clock, the children took the presents and the pram to Perks' house. When Perks came home and saw the pram and the presents, he was angry. He thought people would laugh at him for being poor and needing their things. Bobbie explained that the people wanted to give him the presents because they liked him. Perks calmed down. He was glad that his neighbours thought so kindly of him. The children stayed for tea.
