Very nice, perfect idiom of this part 180 that's not not in the same wavelength. You can see these two persons sitting here a man and the woman I think they are not in the same wavelength. What does it mean? Actually is off for two or more people. So it means to not think in a similar way and we can say to not understand each other well, like my brother and I, we are not in the same wavelength. We always argue and fight.
Let me give us some examples. JACK and Lily are are in the same wavelength. Actually, they always argue and never seem to be friends. That's not good. To my surprise, I found that we were absolutely on the same wavelength about most of the important issues. I cannot discuss anything with her.
We are simply not on the same wavelength which means we are we don't think in the similar way.
