I am Allergic to Rain
I know, it doesn't sound possible, but I am. Something swells up inside my brain right before it rains and stays that way for hours. Not usually before a downpour, but much more during those misty light rains. I get rain brain, which makes me a spaced-out idiot. I made the doctor X-ray my head, but all he found were giant cysts in my sinuses (which they had to yank out of me). I hoped the cysts were the culprit, but alas, no. Rain brain lives on.
