My mum is a big fan of The Six Nations rugby, so often end up watching bits of it with her. I can't say I'm hugely interested in it myself, but I do want England to win, and I always support whichever team my mum wants to win, because I want her to be happy.
I find international rugby is too defensive. They just play for penalties and it ends up being whoever has the best goal kicker wins. So, no, I'm not watching it. Not sure if this is the case during the current Six Nations, but it's a real problem with international rugby in general.
