yeh i assumed he went round the back and just walked into the kitchen and left it there, everyone seems to just walk into others houses using the back door
having said that about getting locked out, although it does seem weird how that happens - being able to get into houses easily til its needed for them to be locked out - i suppose its not completely unrealistic, its mostly the back doors which are left unlocked and they get locked out the front (although surely they could just walk round the back?). our front door is always unlocked so we can just walk in, though our back door locks automatically but my housemate didnt realise that and locked himself out and didnt even think about just walking round the front to let himself in!
