You could try and pretend that this is what you always wanted to do.
Try this, it sounds really convincing: "Flying a nice shiny jet being warm in winter and cool in summer is not what I ever wanted out of aviation. I'd rather fly a C150/PA28/PA38 with a crappy paint job and dodgy avionics. No sir, 8K pa is quite enough for me to survive on and repay my loan for my CPL/IR."
