Oh Liz I am so sorry That must be such a scary thing to happen!!! I don't know what else to say!!!
Do you know how to use the gun???? We keep guns also but you have to know how to use them or they can so easily to used against you. It will surely help you feel safer though!!!
Will the police patrol extra around your house if you ask them? I feel that the police are probably exactly right about the robber NOT coming back as that would be very stupid - but I imagine you feel very violated knowing someone has been in your house and again - I am so sorry to hear that this happened. I hope you have a good night and can sleep OK!
Blessings to you!
