  It is consistent with the measurement of \theta_13 ~ 0.15 by Daya Bay to
suppose that, in addition to being unitary, the neutrino mixing matrix is also
almost hermitian, and thereby only a small perturbation from diag(+1,-1,-1) in
a suitable basis. We suggest this possibility simply as an easily falsifiable
ansatz that has not already been studied, as well as to offer a potentially
useful means of organizing the experimental data. We explore the
phenomenological implications of this ansatz and parametrize one type of
deviation from the leading order relation |V_e3| \approx |V_\tau 1|. We also
emphasize the group-invariant angle between orthogonal matrices as a means of
comparing to data. The discussion is purely phenomenological, without any
attempt to derive the condition V{\dag} \approx V from a fundamental theory.
