Hello, Jack. What are you parents doing?
My mother is making food, my father's installing an alarm system.
What for?
There are some buglars in our area. They're stealing things from our neighbours' houses.
Really?
Yes, and you should tell your parents to do same things.
OK, i'll tell them.
And you should be more careful. You should close windows when you're leaving house. Also, you should check stranger's ID and you should look through peephole if someone knocking in your door.
Thanks a lot!
