I haven’t seen you in forever VS I haven’t seen you forever
I got the answer from my previous question on italki, but let me ask me this question.
I was told "I haven’t seen you forever" is correct.
When I searched "I haven’t seen you in forever" on the Internet, 37,200 results were hit.
On the other hand, 34,600 results were hit by searching with "I haven’t seen you forever".
So does that mean that so many people say "I haven’t seen you in forever" by mistake? Or is it ok to say that in some regions?
Thank you!
