A riddle, You see me quite often, But don’t really care. If you pass by me, You’ll often stop and stare. I can’t speak or see, But don’t think me uncouth, Because no matter what, I always tell the truth. What am I?

You're an educated man so rather than post the answer here you'll find  it by using only the prime numbers in this set.
