When are you returning?

Taranu had come to Mumbai from Gujarat. After spending two weeks, she was going to catch the 11 pm flight back to Ahmedabad on Sunday. While she was in Mumbai, she got a call from her friend Anutara who asked her when she was returning. Since Taranu had some free time, she asked Anutara to guess. So Anutara started guessing -

A: "Monday"
T: "No"
A: "Tuesday"
T: "No"
A: "Wednesday"
T: "No"
A: "Thursday"
T: "No"
A: "Friday"
T: "No"
A: "Saturday"
T: "No"
A: "Sunday"
T: "No"



Now that there were no more options, Anutara was puzzled and she asked Taranu to tell her when she was returning, to which Taranu said -






"I am returning on Sunnight"
