Did she turn the AC on? Wasn't freezing there?

This has actually come up before, so I did some Google-fu back then. Those wall units, while called air-conditioners, provide both heating and cooling as the need arises. Presumably she turned the heat on, lol.

Oh. Okay... I live in Brazil. Here these types of AC are used only for cooling.

Aaah um br! <3
I thought exactly the same thing when I saw that too hahaha :/
