Julia , burglaries in our town have been on the wing .   Why do you say that ?   I heard that a robbery happened in our town several days ago . The robbers ripped off a car in broad daylight .   Thank God , we haven't encountered a burglar . I hope that our house is secure against burglary .   I am worrying about it too . I want to install a security door .   Is the security door useful ?   Yes , I think so . The security door is so firm that nobody can break in .   I totally agree with you . In this way I won't be afraid of the burglar if you are away .
