The simplest way to learn more about your neighbors is to befriend, talk to and directly ask them some of the things you would like to know about them. This may take time and guts, particularly since you are not so sure of their reaction.
There is no better way to learn more about anyone than to make friends with them. Every interpersonal cognitive procedure begins from the first day you say ‘hello’ to the other party. Gradually, you will grow fond of each other and appreciate one another’s company. As the bond strengthens, trust sets in and the already advanced friendship introduces openness. Before long, you will interact freely. It is then that you can ask your neighbor questions.
A point of caution: Do not just unleash a never-ending string of inquiries at first. Acting like a spy may make your partner withhold some of the much-needed responses. Besides, when you are just beginning to know the neighbor better, you ought not to act suspiciously as this may also take a toll on your relationship.
More importantly, this process may take quite a long time because you may not be able to establish a relationship with all your neighbors at the same time. As such, other methods like looking up your neighbors on the social media can also apply. Be warned though, some of these methods may attract legal suits; proceed with caution.
