Random recollection
There was an ad when I was little, for a bathroom cleaner. It's still around, you all know about it - Dow Scrubbing Bubbles, those fat, round-topped little creatures, their feet a whirring of suds too fast to see. The ads still exist. The bubbles are cheerful, smiling, as they swarm across the linoleum and the chrome. But the ads were very different when I was small -- they were ravening, mouths full of teeth, fierce eyes blazing as they surrounded and tore apart germs and dirt. “With Killer Enzymes!” the ads proclaimed, and in my toddler bed I would wake crying from nightmares, sobbing out the word “enzymes” to my puzzled mother.
No ghosts or monsters for me, oh no. I'm the child who was frightened of enzymes.
