Must Be a Sign

Our dog Snoopy has a very bad habit of running away. He could have been Houdini dog! Seriously.
But today Miriam has found the solution to keeping him in our yard...

Miriam: Momma, I'll put up a sign to keep Snoopy in our yard.
Momma: What?
Miriam: I'll put up lots and lots of STOP signs in our yard so Snoopy will stop and not run away.
Momma: But Miriam, Snoopy can't read.
Miriam: I'll teach him.
Momma: But Miriam, dogs can't learn to read.
Miriam in her 4 going on 14 voice: Of COURSE, they can, Momma!

Well, DUH! Guess she told me!
