Answer: Acquaintances
Explanation:
An acquaintance is a person that someone knows, but not so well, that is, they know of the other person's existence and they can get to greet each other and have a brief conversation but it does not mean that they are friends. This type of relationship can occur in any environment, it is common for a person to have a neighbor who is not a friend, but occasionally they greet each other and talk for a few moments. Also at university or school, wherein a classroom some classmates talk for several minutes about anything, but they do not make friends or have a deeper relationship.
Seeing a person on the street that we haven't seen in a long time and seeing them start a conversation for a while makes them acquaintances. They do not have a friendship but they know each other and each time they see each other they greet each other.
