Something is missing

Got this picture from the husband this morning. The car keys have the house key on them, except he'd picked up the spare key, so no house key. Worryingly, within 5 minutes he was back in the house having been able to get in a bedroom window pretty easily! 

Tired happy boys this evening, I had a quick  call with them, the eldest loves a phone call, the youngest cries. Home at the end of the week.
