Pointless conversations with stupid people

I was in the Carp yesterday, watching Barnsley pop my 'if they win the cup I'll be £800 better off' bubble. My Barnsley supporting friend was sitting alongside me, with his fresh out of the wrapping Tykes shirt. I had earlier put on the only red shirt I own, my Coventry away one. This couple sat near us and the one with two X chromosomes started up a conversation with me. It went thus:

'Are you both Barnsley fans?'
'No, just Dean'
'So why are you wearing a Barnsley shirt?'
'It's not a Barnsley shirt, it's a Coventry shirt'
'Oh, why are you wearing a Coventry shirt'
'I thought I would wear something red to support Barnsley who, coincidentally, play in red'
'So who's shirt is it?'
'It's mine'
'Why do you have 'SNOWY' printed on the back?'
'Because that's my nickname'
'Oh, who do you support then?'
Jesus woman.
