Blue ticks in whatsapp Would the blue ticks appear if a person does not have you in their whatsapp contact list?

Although you can see whether the message is delivered, you cannot see their name or status. So I wasn't sure what was the case with whatsapp's new 'read' feature.
You cannot control this thing in whatsapp as of now. Read status is enabled for everyone by default. The only thing you can control is 'last seen status'.
