Visitor Visa - B2

My tourist visa interview was on 27/11 at Karachi Consulate, vo was very friendly, before me he approved visas of two people, they both were my age, one was for student visa and another girl was for tourist visa but she told she had been to usa before, im 22 years old, im stable in my own country, have my car showroom, agriculture lands and properties on rent, my income is 200k as i mentioned in ds160, visited 5 times to uae, and malaysia and Azerbaijan.

Vo: Good Morning with a smile.
Me: Good Morning with a smile.

Vo: why you want to go to us?
Me: The weather is too good now to visit the city like las vegas and the grand canyon desert, and most probably i want to celebrate the new year’s eve at time square, as i want to be the part of ball drop moment this year.

Vo: Do you have anyone in US? Friends? Or anyone?
Me: no I don’t have anyone.

Vo: Which countries you have visited? Was seeing my passport
Me: i told about that.

Vo: You’re not qualified this time, you can reapply again.
Me: ok no problem with smile.

Could anyone tell me what was wrong with my interview?
