That depends, am I supposed to be working?
Assuming by ‘the house’ they mean house of commons, rather than ‘the private comfort of my own 2nd home” then yes you should be working, rather than cackling over some lady(or other, parhaps more specialist) pictures with a coleague.
Or indeed be asleep on the front bench like a homeless person a la JRM.
Maybe the seats should be refurbished with hand rails and metal spikes like they do with public benches, to prevent this sort of tardy attitude from ministers?
Or better still, replace all the commons benches with 45 degree downward angled seats like they do with bus stops.
