That you do think you are not what you are The ironic meaning of this line is clear: Olivia does not think that she is a woman in love with a woman, but she is. However, it seems unlikely that Cesario/Viola means for Olivia to guess the secret, so what does he/she want Olivia to think is meant? Given that Cesario/Viola came as a messenger of love from Orsino, Olivia may take the line to mean "You think you are not one who could ever love Orsino, but you could." If this is the way that Olivia takes it, then her reply, "If I think so, I think the same of you," means "Maybe it's true that I'm not the woman who could never love Orsino, but I also think that you are not the man who could never love me."
