I don't lock them in the car as often as I used to, but I do now and then. Now I will. Just wait.
I lose my keys ALL THE TIME. I have lost whole sets and one of the sets I lost recently had one of the fob keys on the key chain. My boyfriend once bought me a key finder that you put on your desk and put one of the key finders on the keys, and then you can push a button and they beep. It didn't last very long.
I have a lot of key chains on my keys so I can find them better. It doesn't necessarily help. I have done it for all the years I've had keys. I used to lock the keys in my first car when I'd wash the car every Saturday on my parents' front lawn. I learned to make several sets and my "husband" has made extra.
PTSD. Was it hoeing beets? I have PTSD, but it wasn't my childhood I don't believe. Mormonism set me up for PTSD.
