I'm sorry. I have the sense of humour of an 12 year old (I'm nearly 50) and I couldn't stop a little smirk at the idea of how many collective heads would explode reading that title. I'm a bad human being. I've had a trying day at work and my commuter train is like being a sweaty human Spam (the meat-amalgam obelisk thing, not the email junk kind). Forgive me, Mumsnet, I am being a wanker. Feel free to roast me.
YABU: Yes, you are indeed a wanker. One more grandparents thread and I'll start biting people.
YANBU: You are still being a wanker, but we are all permitted one small bit of stupidity to brighten our shitty commute.
