You are NOT obligated to tell them anything. Whatever they ask, just brush their stupid questions aside. Roll your eyes and tell them you accidentally found some sites and mentioned it but honestly you'd rather spend time shopping online, etc.
Never admit to anything. Being honest will get you absolutely nowhere. Better to act like a dumb blonde and giggle about it than be honest.
Trust me, honesty got me DF'd when they had NO PROOF that I had ever done anything 'wrong' in their book.
