In my building there lives a nice girl, practically in an apartment above me, we only say "hello" to each other; one time I noticed that her car didn't move for weeks, nor I saw the girl herself, so involuntarily I started to worry that something was wrong with her and regreted that we weren't friends on social media. Finally she showed up, turned our she got a second car, and I only said my casual "hello". Sometimes people ask for favors while not really being interested in your personality, it's certainly not a friendship, I think such experiences stop us from getting closer with people around us, we don't want to be a bother ourselves, but in a way this kind of policy only insures that our contacts will be of pragmatic nature...
In other words, I'm glad that Zuki is fine :-)
