Today as I stopped at a traffic light, I glanced over at the house I was next to and saw that their windows were frosted glass. And it made me feel really sick. I have no idea why.
Other triggers:
cat food (not surprising)
the smell of my car (bit of a problem this one)
the mention of mayonnaise (especially as 'mayo') (just typing that wasn't fun)
I think I'm going mad.
