Final answer:
Marji's family and similar characters held parties as a way to escape harsh realities, maintain normalcy, and enjoy social connections despite dangers.
Step-by-step explanation:
The narrative excerpts provided suggest that Marji's family, and characters in similar situations, continued to hold parties despite the associated dangers as a form of escapism, to maintain a semblance of normalcy, and to assert some control over their lives amidst chaotic and oppressive circumstances.
These gatherings were perhaps one of the few ways they could exercise personal freedom and retain their social identity. This defiance against restrictions and the desire for human connection also reflect a deeply ingrained aspect of the human condition – the need to seek companionship and joy even in the face of adversity.
