What are you totally, insanely insistent about... that most people might think you were nuts for?

Do you have a certain, odd/quirky way something needs to be done? A little habit that you have to do or you feel lost? Maybe something inconsequential to most people but it’s just the only way for you?

I ask this question because I realized a mania this morning: strawberry chapstick. I’m sick and so my lips are terribly chapped. I went to the store this morning before work for strawberry chapstick, and had to go to three different stores to find strawberry. I will not use cherry, or the plain black one. I will not use Blistex or Vaseline Lip Therapy or SoftLips. I will only use strawberry chapstick.

Then I realized I was probably an idiot. I would like to hear stories from other people so I know I might not be too much of an idiot ;)
