When you're finished using your Google account,
you'll sign out.
Signing out of an account closes what you were
working on. You won't be able to see or work on it
again until you sign back in.
Signing out of an account helps keep your information
secure.
If you don't sign out, someone else that uses this
computer may be able to use your account.
BUT:
Since there is more
work to do today, it is important that you DON'T SIGN OUT RIGHT NOW!
