Yeah I can relate so hard to this one.
It aways starts off the same way, "I'm running a little late but it'll be ok." Queue sticking your hand into your pocket to lock your front door and being met a distinct lack of the familiar 'jingling' and that terrible sinking feeling of dread when your hand closes around air.
As panic sets in you set about to destroying your entire home as you frantically search for your keys.
Like I said. I can relate.
