Returning brother

'My long lost brother is returning on Sunday. I haven't seen him since he left Ireland thirty years ago,' said Mick. 'He wrote to say he'll be arriving at Shannon airport at eight in the morning.'

'If he's been away that long,' asked Sean, 'how will you recognise him?'

'I won't,' reasoned Mick. 'But he'll recognise me cos I've never been away at all.
