I think the football shiz is another way for her to get closer to sb, i think so of the silence was due to rehab as a proper inpatient this time and she has recenty been let out( i think the rehab was more mental health than drink or drugs) and she is trying to make up for lost time with the boy ( who if my estimation is right is about 14 , the same age as my nephew, who currently has his own set of mates and a steady girlfriend and hobbies. My sister is merely the taxi driver and food maker.) I can honestly see her being the moat over the top mum( think mean girls) and literally being totally embarassing( and no pet,not in a cute way)
