May I Borrow a Cup of Sugar?

A character comes over to borrow a cup of sugar, or something else like flour, a hedge strimmer, or whatever from their neighbour and this is used to set up a plot thread of some sort:


 * As a Meet Cute
 * When something is happening really needs keeping secret and neighbor honestly needs to borrow something but has epically bad timing
 * Similar to the above, but an excuse to barge in their neighbor's business because they suspect something odd is going on and they are a Nosy Neighbor
 * The borrower has just stumbled onto the home of a serial killer and this is the last we'll see of them alive
 * To set up the plot in some other way

Please note this is not just a list of instances of neighbous borrowing things in fiction as this has no meaning in itself; it has to at least set up a plot thread or joke of some sort.

He almost forgets to also buy some milk so she can borrow it.
