I had to concede to a believer “Perhaps you are right”

Yesterday a friend of mine confronted me regarding my atheism.

We had quite a long, involved and heated discussion and at one point I said to him:
“You are a very intelligent person, in fact far too intelligent to believe in god”

His immediate response was an angry:
“I most certainly am not”

I let that hang in the air as we both silently pondered its truth and I finally conceded:
“Perhaps you are right”
