The flowing sadness
There is a saying that goes:
{Our parents leave us early, and our guardians and spouse respond to us late but, our siblings are the only ones who stay by our side.}
A statement similar to this one was displayed for the two sisters.
Even though their mother had left them and gone somewhere, these two sisters were the wall and roofs remaining for each other.
Thou, both were arguing among themselves however, tears, a symbol of flowing sadness, cooled down their rage of ignorance among them.
