Is visiting a neighbor, with whom you have no rapport, for mere minutes, considered a dereliction of her rights, and what are her rights over me?

The right of a neighbor is to maintain ties with them, treat them kindly, and refrain from harming them. It is not a condition to love them or befriend them. It is sufficient for maintaining ties to visit them and inquire about their well-being, even if briefly. This should be done in accordance with what is customary.
