Hey, Neighbor!

I live in a building with 24 units. Most residents are friendly. The owners of two condos, however, do not respond when I say hello to them in common areas. I have finally given up and taken their lead: I walk by wordlessly. Is this right?   —T.L.M.

What’s better than the easy bonhomie of a neighborly acquaintance? So little effort, so much goodwill! Your silent neighbors seem to feel differently, though. It’s probably not personal. If this really bugs you, try introducing yourself. The additional data may tip their scales toward “Good morning!” Or simply accept their deep introversion (or serious lack of interest in you). There’s no law that mandates lobby greetings.
