2020年-高考英语-全国1卷-完形填空【寻求原文出处】

Since our twins began learning to walk, my wife and I have kept telling them that our sliding glass door is just a window. The reason is obvious. If we admit it is a door, they’ll want to go outside constantly. It will drive us crazy. The kids apparently know the truth. But our insisting it’s merely a window has kept them from attempting millions of requests to open the door.

I hate lying to the kids. One day they’ll wake up and discover that everything they’ve always known about windows is a lie.

I wonder if parents should always tell the truth no matter the consequences. I have a very strong fear that the lie we’re telling is doing spiritual damage to our children. Windows and doors have important metaphorical（比喻） meanings. I’m telling them they can’t open what they absolutely know is a door. What if later in life they come to a metaphorical door, like an opportunity（机会） of some sort, and instead of opening the door and taking the opportunity, they just stare at it and wonder, “What if it isn’t a door?” That is, “What if it isn’t a real opportunity?”

Maybe it’s an unreasonable fear. But the bottom line is that I shouldn’t lie to my kids. I should just accept repeatedly having to say, “No. We can’t go outside now.” Then when they come to other doors in life, be they real or metaphorical, they won’t hesitate to open them and walk through.
