Also, when you always, ALWAYS bring a banana to a party.
When you have a note taped to the door of you bedroom telling your faimly what to do if you become the Doctors companion.
When it's literally the thing you think about most. :D
When you always go out with a toy sonic screwdriver in case some monsters arrived and you need to save the day... (I'm doing that... only 1 person has noticed that it's from Doctor Who!)
When you got your cousin and best friend to be obsessed with Doctor Who (okay, my cousin only likes it because she thinks the Doctor is cute)
When you had a major argument with your friend because they wouldn't accept the fact that his name isn't Doctor Who, it's the Doctor.
When you get up super early to catch an hour of Doctor Who before school.
This is AMAZING!
You buy life-size cardboard cut-outs of the characters and throw them birthday parties...!
When you think your air-conditioning (momentarily) sounds like the TARDIS materialising... :P
you're watching the Timey-Wimey Special
when you spend every night dreaming of going on adventures with him and your days are spent listening for the tardis vwarp. yeah... then you know your obsessed.
