The clue is in the name, it's a shit suburban town just outside of Greater London. Mostly inhabited by people who live in caravans and have on average 2 GCSEs. Sure there's a few London buses that serve Staines, but they just take you to even shitter places like Hounslow and Hanworth. If you're making the effort of leaving Zone 6 to go to Staines, make that extra trek and go to Windsor which is slightly less shit. Staines is most famous for being the home of Sacha Baron's Cohen "Ali G".
A person in your life you can't get rid of or deny knowing. Other aspects of your life are fine, but there lies a big old reminder and someone is always pointing it out. Every time you look at him/her, you wish your life was stain-free.
