Meaning: you’re blocking my view. Use examples.
Rewrite 1: I could see [the TV or whatever] if you’d open the door in your back
Rewrite 2: when did you grow that door in your back?
Rewrite 3: what if people were windows – think I could see through you right now?
Rewrite 4: did you just grow a foot wider, or are you actually standing in my way?
Comment: This cliché isn’t as much about writing as it is speaking to someone. Still, there are a lot more creative ways to tell someone you can’t see through them.
