hubby has done it, not me. I have this OCD issue with keys. I Check 3 times before I get out of the car and close the door and then I will feel for them in my pocket. Same way with the house key. And I will hit the lock button 2 times on the car, just to be sure.
I've been locked out of our house. There was a time when there was always someone home so I didn't have a key. One Sat. morning- guess what- they were all gone! I come home with bags of groceries and sat on the front steps until I could find somebody close enough to come and let me in. Thank goodness for cell phones. I now have a key since my daughter moved 2 years ago. I guess I was grown up enough to have my very own. We still laugh about it.
