Why does my wife always leave the door open behind her?

This is a weird thing that I don't think I've talked to her about before, but she always leaves the door open every time she leaves the house.<br><br>I'm no therapist, but I'm sure she's got ocd. Based on the fact that she always locks every door twice. So I assume she's aware that the door should be closed. She won't even leave the house until she knows that the doors are all locked. But for some reason she always leave the front door open.<br><br>It's not a big deal. I just wonder what runs through her mind when she leaves the house with the front door still wide open.<br><br>Edit: she always leaves the front door open but always locks it. Shes got this thing called smart lock where she's able to see if all the doors in the house is locked or not and where. She always double checks before she leaves the house. 2 min later shes 1/4 of a mile away and I can see the front door wide open but she knows that it's locked. Shes got ocd.
