I like to think of mine as a pimple on my marriage: ugly, painful and full of nastiness. When you pick at them, they only get worse, but leave them alone- and they go away on their own. (and it kinda gives me a giggle to visualize her head as a puss-filled, red irritation... Can't wait for it to pop!!)
Purg - I admire your creativity but wow this is gross!
