I leave the house at 7 every morning and don't usually get in until 7 at night. He works two minutes from where we live and drops the children off at school and picks them up from the after schoolclub.
He can't understand why I am so tired all the time - "FFS, all you do is sit on a train and then sit at a desk and push a few bits of paper around - what can be so tiring about that?" - and gets cross when I refuse to cook dinner when I get in.
