My kids have a cellar phone for kids.
Two daughters have the same cellar phone. Of course, they can't use it at the same time.
The phone is gone somewhere.
Who is the last person to use it?
When is the last time to use it?
Neither of the kids remember.
One of them must misplace it somewhere.
When we try to find something, it's hard to get it.
It 's like a hid-and-seek.
Maybe we'll get it when we forget to find it.
