I've sat between two people in similar situations. I didn't consider them rude for interacting or passing items back and forth a couple of times. It is the risk you take when you don't pre-select a seat.
If the demand of the self-appointed internet judges of manners and etiquette is that people sitting aisle-window should not speak to each other for the entire flight and never pass anything then they are going to be sadly disappointed.
