めちゃくちゃ寒いもん : Because it is freezing, or because it would be freezing? **** In the conversation above I am unsure of what is meant by . From what I can see, this could either be interpreted as : 1) If the windows were opened then it would be freezing 2) It is freezing, therefore the windows shouldn't be opened (because it would become even colder). Whilst they both revolve around the idea of opening the window making things colder, they focus on different things. Could someone clarify which of these (or any other) ways is the correct way of understanding this utterance in this context?

From the following context:

Taruhi: We couldn’t open the window.

Miharu: We don’t need to open the window. Do we?

Taruhi: Yes. I completely agree with your opinion. (Because) it’s terribly cold (outside).

Mihashi: Both of us are seated in the window-side. It’s so cold over there.

I take the part in question - for “(because) it’s terribly cold outside, (and we’ll be frozen with flow-in of cold air, if we open window.”

“” apparently refers to the present status, and not the situation that can be supposed to happen after opening the window.
