Dear Queenie,
My girlfriend cannot seem to learn to lock the door of our apartment and I worry that some thief might just walk in when I am not at home or when we are both out.
Queenie, how can I get her to learn to always lock the door?—Worried boyfriend
Dear Boyfriend,
You could hang a sign “Remember to lock the door” on the door, but even that might not be enough.
But your apartment should have an automatic lock on the door to the outside, and as it does not, you should have one installed, even if the landlord will not do it and you have to pay for it yourself.
