You know you're addicted to Alton Towers when:
If you overhear strangers in a shop or somewhere saying something as innocent as "the door closes behind you", you lose all inhibitions and having jumped to the conclusion that you know what they're talking about, you invade their conversation, by saying something like "Oh yes, Th13teen at Alton Towers?" (I can't fight the urge to do this!)
When your 3 year old child knows the names of the all the rides and your 6 year old knows the height, speed, age and manufacturer of a number of the rides.
If you work shifts, but have been known to go to Alton Towers in the morning and then drive straight to work for an evening shift.
Also, you know you're addicted to Alton Towers when you can't resist replying to a topic entitled 'you know you're addicted to Alton Towers when'.
