Captain Jonathan Archer:  Whatever friction there 's been between us , I 'd like to try to minimize it .
Sub-Commander T'Pol: Friction is to be expected whenever people work in close quarters for extended periods of time .
Captain Jonathan Archer: I guess that 's always been true , especially when the people are of the opposite sex .
Sub-Commander T'Pol: Then it 's good that you 're my superior officer , that we 're not in a position to allow ourselves to become attracted to _ one _ another , hypothetically . If we were , the friction that you speak of could be much more ... problematic .
