peanut butter and OCD

Today while washing dishes I had to encounter one of my most hated smells ever: the combination of hot peanut butter mixed with dish soap. I tried to figure out why I hate this smell so much, and my thoughts went back to my childhood and my mother's obsessive compulsive disorders: one of which was making sure every piece of recycling (plastic jars, metal cans, etc.) was thoroughly soaked and cleaned before put in the recycling bin. In particular, she wanted peanut butter jars to be clean, so she would fill the jar with hot water and dish soap and let it soak on the kitchen counter for hours. I don't know if this was some ingenious plan she had, or if it was due to pure laziness in regards to actually scrubbing something to get it clean. Anyway, I don't really see the point in cleaning recycling materials, since they are melted down to nothing and sterilized before they are used again. Still, this doesn't explain why I hate the smell so much. I must just relate it to bad memories of my mother. That's right, I heard it straight out of my psychologist's mouth, I am allowed to blame my mother for most of my psychotic quirks.
