I love Clare's 3BT very much, but sometimes you just have to grump, so here goes. This will be an anti-3BT, if you like.
1. Bad grammar. Your and you're are not interchangeable, neither are there, their and they're.
2. Commuting is dull. I'd been pepping it up for the past few months by travelling illegally - my season ticket was London to Staplehurst, when it should have been London to T Wells. (This is only a different route for the last 10mins of the journey, and I really couldn'd be bothered to change it. The price was the same for both.) But it expired and my new ticket is for the right route. My flicker of excitement as I approach the station is rapidly dulled these days by the realisation that I don't have to be scared of the conductor any more. Rats.
3. Bloody numpties. Why am I surrounded by them??
Special bonus addition:
4. Cover versions of pop songs. About half of the music they play in the gym is a cover of stuff I remember from when I was at school. Write something new, you bubblegum pop mannequins!!
