"The mirror in my room, I brought it there. True or false?"
I had a brilliant strategy. By asking five absolute true or false questions initially, I could force Joeveirian to expend his lies or truths right away.
This way, no matter how he answered my last five questions, I would be able to know if he was being honest or not.
In simple words, here's an example:
I could just ask, "You are a man. True or false?"
If he chose to lie and said "false," I would follow up with another absolute question like, "Earth is round. True or false?"
This would force him to lie again or tell the truth. If he continued to lie and replied with "false," he would have used two of his five lies.
Just like this, if he decided to be truthful and answered those questions as "true," I would know he had used up two of his five truths.
