I'm glad you're OK. It's so scary to think of all the "what if's".
I bought a storm door that locks so that I have two separate locks on the front door.
If the garage door is open I make sure that the door leading into the house is locked.
I hate being this way but we really have no choice these days. The ONE day I left the garage door to the house unlocked wouldn't you know my police officer son comes waltzing in with a lecture for me to
keep my doors locked!
