Suppose, for example, that a child is watching his dad come home from work. She can't wait any longer to show what she's got, so she goes to the window and shows her new teddy bear to her dad. How can I say "she showed it to him from the window" in Latin? The bolded part is what I am unsure about.
I can see various options, but I can't tell which, if any, is correct:
Illa id huic monstravit ex fenestra.
Illa id huic monstravit in fenestra.
Illa id huic monstravit a fenestra.
Illa id huic monstravit per fenestram.
Illa id huic monstravit fenestra.
The pronouns are irrelevant for this question. Is there an (attested) idiom for doing something from a window, be it showing a teddy bear, singing a song, or greeting a friend? If different actions require different choices of words, I give precedent to the example given above.
