meeting mamaji, is it wrong?

I don't understand whats wrong with all of them??? It was a park and anyone can come there.. Why was sadhana even worried that she have to tell vasu abt tat? She met her mamaji, not some stranger or like young man? Why do avni and vasu have to make this a big issue?? Is it wrong to meet someone frm MAAYKA outside the SASURAL? Yeah mamaji askd her to meet him there, but why don't they can think other way around tat they might have met accidentally?? I am just soooooooo irritated with SADHANA, VASU and AVNI ( as always) 😡 😡
