"Just to be very clear, here, I wasn't saying there was anything wrong with fixing planets! I'd fixed three before I got into Milliways! That's a perfectly reasonable foundation on which to build a relationship! You just want to make sure you also have things to do when you're tried and winding down at night, and that you know you'll have other things to do when you're done fixing the planet so that neither of you is tempted to dawdle or hold off about finishing that."
Thellim doesn't want to dump on Velgarth in the process of doing relationship therapy!
