What does 'I'm calling it' mean? (I am asking with the context~) I heard this expression on an American drama, 'The Office'. A girl was wating for a guy she went on a date with few days ago to call her back. But he did not call back and it seemed like he wouldn't call her back. So, she said, 'oh, I am callling it, guess that's curtains for the yoga guy' I guess it means, 'oh, I will give it up, guess it is the end between the yoga guy (she met him at a yoga class) and I.' am I right? help me ~
