'Darling, would you like to grow a beard?'
'Would you like me to?'
'It might be fun. I'd like to see you with a beard.'
'All right. I'll grow one. I'll start now this minute. It's a good idea. It will give me something to do.'
Catherine and Henry discussing whether he should grow a beard, in Ch. 38 - A Farewell to Arms (1929)
