You explain to Palak about menstruation, trying your best not to make it sound too scary or embarrassing. You reassure her that this is a natural process and something all girls go through when they become women. You emphasize the importance of keeping herself clean and using proper hygiene measures during this time.
As you finish talking, a wave of nausea washes over you. The realization hits that Palak's lack of friends and limited social interactions could be due to her having no one to talk to about such things.
