I can't find my car keys or house keys.
I got home from work last night and opened the door, so I had them then. I didn't go anywhere last night, but they aren't in my bag or any of the other usual places I leave them, and I have no idea where else to look for them.
I don't have my spares either because my son has them with him.
I can't even think where else to look, and I am now officially going to be late for work.
