OCD adventures

As previously stated, I am obsessive to the point of borderline insanity about some things (the Sheldon Cooper comparison is constantly made).  Last night some friends popped over while I was cooking dinner, and the conversation below occurred followed by utter confusion.  On the bright side, at least my friends know me well...

Me: I have to go to the shops, damn it!
Friend: Wait... what?! But it's TUESDAY?  You know it's Tuesday, yeah?
Me: Yes I know, but I forgot to get basil pesto for the soup I'm making.
Friend: But... it's Tuesday.  You don't go to the shops on Tuesday, you go to the shops on Monday. 

This is true.  I should explain my friends confusion; as stated, I go to the shops on Monday.  And I am so obsessive about my routine that the slightest deviation from it usually results in an epic, epic, epic tantrum from me.  It was more the lack of tantrum which left her confused, and that was fine until we got to the shops...

Friend: Are you okay?
Me: It's Tuesday...
Friend (sensing the danger): Yes, but you needed pesto, remember?
Me: Yes but it's Tuesday.  WHAT THE HELL AM I DOING AT THE SHOPS ON A TUESDAY?! I DO NOT GO TO THE SHOPS ON A TUESDAY, I GO ON A MONDAY! ARAGGGGH!!!!

This would be around the point my brain started a slow implosion.  First over the deviation from routine, second because I'd left half made dinner on the bench (because I needed the pesto to complete it) and that's also something I don't do, and third because... well, because it was Tuesday.

Eventually we made it back home and my stress levels dropped and all was well.  When we sat down later to relax, as much as I tried to resist the urge, I couldn't

"You know that's my spot, right?"
