I liked it, but it seemed to be about nothing
All I can say is that this was very crystal clear and fabulous artwork and a lot of time went into this. The story though, hmm, I'm not really sure what he was doing in the barn.
One note about the key hanging outside the door. If Nim is so trusting, then the question is, Why lock the door in the first place. I grew up in a small town and we never locked our doors. Also in the movie Bowling for Columbine the people of Canada didn't lock their doors either. Its not that we're not trusting, but if you have insurance against burglary then you have to lock your doors or the insurance doesn't have to pay up, because you were the one being negligent. It only takes one time getting robbed to get nervous about locking up no matter where you are. Its better to be safe than sorry is the proper cliche here.
