As I have a dog that is a great escape artist and have a habit of sometimes taking herself out for a walk, then yeah, I make sure that the door is always locked
Only problem is that she has figured out of to turn the lock and open the door, so I have to not only lock the outer door, but the door leading to the entry area as well.
1) Do you lock your door when you are home during the day?
Yes, see above.
2) Do you ever forget to lock your door at night?
Yes, see above
3) Do you keep your windows shut during the day?
Unless I'm venting, then yeah. But only when I'm home.
4) Do you ever leave windows open at night?
If its warm enough outside, then yeah, I'll leave the windows open on hot summer nights.
