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 41 is obvious. If we 42 it is a door, they’ll want to go outside 43 .It will drive us crazy. The kids apparently know the 44. But our insisting it’s 45 a window has kept them from 46 millions of requests to open the door.
I hate lying to the kids. One day they’ll 47 and discover that everything they’ve always known about windows is a 48.I wonder if 49 should always tell the truth no matter the 50 . I have a very strong 51 that the lie we’re telling is doing 52 damage to our children. Windows and doors have 53 metaphorical（比喻） meanings. I’m telling them they can’t open what they absolutely know is a door. What if later in 54 they come to a metaphorical door, like an opportunity（机会） of some sort, and 55 opening the door and taking the opportunity, they just 56 it and wonder, ＂What if it isn’t a door?＂ That is, ＂What if it isn’t a 57 opportunity?＂
Maybe it’s an unreasonable fear. But the 58 is that I shouldn’t lie to my kids. I should just 59 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 60 to open them and walk through.
