Alia Bhatt calls the Help Desk to complain a computer problem. 

Alia - When I type computer password, it just shows star star star star. 
What's the problem? 

Help Desk - Dear lady, those stars are to protect you, 
so that if a person is standing behind, he can't read your password. 

Alia - Yeah, but stars appear even when 
there is no one standing behind me.
