The other day a maintenance man came to our house to repar something, and he said he'd do a safety inspection while he was here.
So he checked the smoke alarm and fire extinguisher, and cleaned the air filters, and then he asked me if we'd had safety sickers installed on our upstairs windows.

I didn't know what he meant, so he showed them to me.
It's a good thing he installed those safety stickers right away.
That will keep those kids from falling out of the window.
