"I haven't waited long." or "I haven't been waiting long."?
Present perfect or present perfect continuous?
- Sorry I'm late.
- That's all right. I .................. (not/wait) long.
In my opinion, both Present perfect tense ("I haven't waited long.") and Present perfect continuous ("I haven't been waiting long.") are all right, but I am really not sure.
Can I have your help? Thank you in advance.
