So, Susan left for the mountains she loved so much and Helen stayed at home in London. Helen`s mother saw that her daughter was lonely. She bought her a beautiful collection of stamps and coins. The coins were in silver boxes and the stamps were in a large album. But Helen didn`t think much of her collections. Collecting things was not her hobby at all. Then Helen`s mother decided to take her to the theatre. Helen was not a theatregoer but she liked theatre very much. From the seats which were in the stalls she could see the stage very well. She could see the actors on the stage and the scenery which was fantastic. She liked the performance very much and said she would like to take part in it. Whenever Helen`s mother could she always bought tickets for this or that famous play. But usually Helen stayed at home. She read a lot. And yet Helen was very weak and it was difficult for her to walk. Life in the city didn`t do her any good.
