Mum How are you liking it down the mine, Ken? Ken Oh it's not too bad, mum... we're using some new tungsten carbide drills for the preliminary coal-face scouring operations. Mum Oh that sounds nice, dear... Dad Tungsten carbide drills! What the bloody hell's tungsten carbide drills? Ken It's something they use in coal-mining, father. Dad (mimicking) 'It's something they use in coal-mining, father'. You're all bloody fancy talk since you left London. Ken Oh not that again. Mum He's had a hard day dear... his new play opens at the National Theatre tomorrow. Ken Oh that's good. Dad Good! good? What do you know about it? What do you know about getting up at five o'clock in t'morning to fly to Paris... back at the Old Vic for drinks at twelve, sweating the day through press interviews, television interviews and getting back here at ten to wrestle with the problem of a homosexual nymphomaniac drug-addict involved in the ritual murder of a well known Scottish footballer. That's a full working day, lad, and don't you forget it!
