Oh my goodness, this story is completely and totally adorable. I will now go read the originals and tell you how awesome you are for writing River/Jayne that is both funny and touching. I think my favorite promise may be: "I also promise to discuss major decisions, like robbing banks or going to see my mother, in advance of said event occurring. "

All of the parenthetical remarks are great, especially the guns and knives stuff. Thanks for posting!
