When's Mum coming home?
Will she be home soon?
I'm getting hungry!

Dad: Heavy sighs from Pooch, punctuated with sitting bolt upright to look eagerly out of the window every time
he heard a passer-by. Pooch's 'belly clock' is accurate - but Poochmum was running a bit late this evening.
She did get an enormous greeting from Pooch when she eventually returned home though. :-)
