Newbie seeking some experienced advice

Hi Nick, I think it is your demeanour that's important. If your demeanour was pleasant with your W during that interaction, I think it was perfect. If your demeanour was cold, and you were unsmiling, it may have come off as rude or reactive.

So, keep aiming for brief, pleasant, 'neighbourly' - I'm a guy with lots on and you are not central to my plans here - but never in an unpleasant, abrupt, cold way...
