Let's make a deal

I know I've touched upon this before, but I can't get over how callous these people are to something like sex!  I can understand it a little more when it was Kathy and some random guys at the cottages.  But she lovedTommy, and even that she made seem like it was some business transaction!  Kathy doesn't say that she and Tommy had sex because she loved him, because she was ready and she wanted to.  In her words, it was because "if our plans went along the lines Ruth had wanted, and we did find ourselves going for a deferral, it might prove a real drawback if we'd never had sex" (Ishiguro, 238).  How romantic?  It would have been an inconvenience for them to not have had sex when they approached Madame, so they might as well get it over with, right?  I just don't understand that.  Miss Emily said they used the kids' art to determine whether or not they had souls.  Maybe they should also have taken into account whether or not they had any remote feelings of reverence for sex or love for the one they were having sex with!
