A while back, you were diagnosed with a rare never before seen medical condition that doctors have called a "Shrinking Trigger".

This condition makes it so that whenever you get complimented, you shrink with the limit of how small you can be being 1 inch tall.

Since this condition has never been seen before, there's no way to cure you of it so you just have to live with it for the rest of your life. At least you grow back to your normal size in a week.
