I was always the bane of my grandfather because this was me and sports

Best way I found to see who people root for with out looking like you know nothing about teams. Is ask: "Who is winning?" If it is their team they will be up beat with the answer if the other team is winning they usally sound angry or say how many points their team is behind or just cuss and say the teams name.
