since some doors and windows and such can be blocked by boards now, what if the neighbor could block stuff himself?
in the neighbors hideout (the bookshelf place) there would be a stack of boards (you can grab 1 or 2 and they take up inventory space) and you can use these to block doors or windows to your liking. however, there are a limited amount of these ( 5-4? ) and cant be taken back once you use them.
if the neighbor drops these, kids can pick them up, but they cannot use them.
