Maybe you're not keeping them out. Maybe you're keeping yourself in.
Yes, yes, we all know the purpose of gates like this. Gates like this are supposed to keep the animals and the children away from all the things they'd find dangerous and enjoyable. Gates like this are made so that you don't have to worry about if your kids and pets are wandering about in strange places.
But what if that's what they WANT you to think? What if these gates are all a plan… designed by animals and children!
No, don't react. Stay calm. Don't let them know. Act like everything's normal. Buy one of these gates and shout out loudly "HEY I JUST BOUGHT THAT GATE ON KIDS.WOOT TODAY" so they don't suspect. When it arrives, set it up. Pretend to walk into the other room. But don't. Hide and watch. Watch what those animals and children are doing when they think you think they're safely gated away. Take notes on what you see. Report back. Use a code.
That's the only way we're ever going to find out the truth.
