See I don't get folk like that.
This is how conversations I have go:
Me: Did you watch Strictly?
Them: Oh, no, I don't watch it
Me: What did you get up to? (or similar)
Although I have colleagues who do ask if I watched [name of show I don't watch] and when I say no, proceed to tell me all about it with me, when they've paused for breath, saying again I don't watch it.
Your secret will be safe with us 
It would seem Mighty Mighty Monkseal is a JP fan too
