I: Not yet

I: I will
M: Do that
I: I am
M: Mix the lube with oil
I: I'm going to use just the lube
M: with oil
I: ...
M: with oil
I: ...
M: Are you going to put on more than that?
I: I put on this much
M: Maybe more?
I: This is how much I put on
M: I don't think more would be bad
I: ...
M: That looks good the way you did it. Should we go ahead and put this together?
I: I thought we were going to stop here
M: Don't you want to put it together (holding torque wrench)
I: ...
M: Lift your end of the crank
I: I am lifting it. Be careful.
M: I am being careful
I: Gently
M: ...
