At around 45 or 50, perhaps you both have all the time to talk. You can sit facing each other in the dining table, without the choosy, picky, whiny toddler demanding for that one food which you have never tried before; without a bunch of noisy little people fighting over who got the big piece of the cake and without the constant buck buck buck cross talking which has never let you complete a sentence to each other. Yes, when your kids leave home, you have all the time to talk. Yet, this could be a phase when you do not know what to talk, other than how home is without children and how worried you are thinking of the life on their own.
