What did I learn today?
That it is not safe to watch an Andy Murray match with me. I nearly assaulted my mum when she made the innocent mistake of thinking a ball had landed out, when in fact it had landed in.
Bloody hell, my mum's exactly the same - 'was that out/in?'
CAN YOU NOT HEAR THE FREAKING LINEJUDGE AS I SEEM TO BE ABLE TO?!?!
Can't say I've ever wanted to uppercut her though.
