A more complex version of this line appeared in someone's cover letter. I found it odd for some reason but I can't be sure what that reason is.
I am a girl into music and art.
I corrected it to "I am a girl who is into music and art." which sounds better to me. I would like to know if the original works. On the other hand, "I am a girl into my late 20s." and "I am a girl into my my fifth month of pregnancy." both sound natural and idiomatic to me, so is it just me?
