The images that are running through my head...
Run! Jess! Run!
I don't hold it any longer then I need to. I can and will hold it if the nearest toilet is disgusting or if I know I will be home soon. Otherwise, I go when I it's ready.
I need a new suitcase, my old one is about six years old and it needs some serious repairs. When was the last time you bought a suitcase and what does it look like?
