Thor: If you knew where he was, why didn’t you call me?

Doctor Strange: I have to tell you, he was adamant that he not be disturbed. Your father said he had chosen to remain in exile. And you don’t have a phone.

Thor: No, I don’t have a phone, but you could have sent an electronic letter. It’s called an email.

Doctor Strange: Yeah, do you have a computer?

Thor: No. What for?
