I did, in fact her refusing to engage in any sort of conversation whatsoever regarding a motorbike, I actually hopped on the interweb (Richard Rawlings from Gas Monkey Garage termination) and bought a 'T' shirt which says exactly that.
Only difference is my writing is on the front so, every time she sticks her nose in the air when I mention the banned word .................. "bike", I run to the bedroom and out it on. And, stick my chest out.
