Explanation:

Elephants are social animals. When elephant families reunite after being apart, they do not act like strangers (they have social bonds), they do not start to fight (as they are family and not in a hostile situation), and they do not feel sad and cry in a negative sense (elephants show positive social behaviors when reuniting). Elephants are known to greet each other with various social behaviors like touching, vocalizing etc. when reuniting.

They greet each other.
