"Why not?  I'm solvent, I've got a fairly good job, I'm in good health - or I will be, as soon as I get their condemned 'truth' drugs washed out of my system... and since I haven't, quite, I feel an overpowering compulsion to tell the truth right now.  I love you.  I want you to marry me and let me rub your poor tired feet.  So why not?  I don't have any vices that you don't share with me and we get along together better than most married couples.  Am I too old for you?  I'm not that old!  Or are you planning to marry somebody else?"
