Will I, Won't I?

Tomorrow's Saturday. Wifes schedule, which involves me because I'm the driver and the wallet,- a.m, go shopping in Dewsbury market and grab a quick lunch there.,- p.m, go shopping at supermarket for weekly groceries., - evening, spend a boring night visiting relatives.
Now I know I've got a VCR, but will I or won't I get to watch the qualifying session for the British Grand Prix? I'll let you know.
Question- Why do wives who fall asleep in front off the telly, uncannily wake up when you turn it over for the football and say, "What yer doing? I was watching that."
