File under 'Stupid questions'

We have the sister-in-law staying with us at the moment. (Still. Will she ever leave?) Anyway, last night whilst tucking into my dinner, I asked if the ladies would mind if I changed channels to Sky Sports 1 so I could see the scores come in. They voted in favour of my proposal. I really should have gone to the bedroom to watch because for the next 45 minutes i had the s-i-l inflicting her pearls of wisdom on me. I didn't realise she knew so much about football, or rather talk incessantly about it without actually getting one fact correct. The score I had been waiting for came up 'Coventry 1 Southampton 0'.
'Yes' I cried in a voice too loud for polite company.
'Oh, you support Cuventry (sic) do you?'
'Indeed' I replied ('and I would appreciate it if you could shut the fuck up for 15 seconds whilst I enjoy the moment' I thought)
'I have a friend who comes from Camden....' she droned.
Anyway, moments later, up pops 'Barnet 1 Swindon 0'
'Is Barnet a different team to Coventry?' she asked.
'??????!!!!!!'
