On their way out the door back to college, one-on-one, I gave each of our two kids a copy of 'Cupid's Poisoned Arrow.' Both were surprised, but seemed appreciative. Of course, if my wife ever finds out that I did this, I will be in the dog house for a long time (she is a good and caring person, but is private and not a believer -- just a cooperator -- in Karezza).
I look forward to chatting with the two over time on the subject. I think it is really important -- maybe the most important personal intervention there is; for me, it has been much more effective than meditation and 'positive thinking,' e.g., trying to remember to 'not get angry' -- and I think the practice will put them in a better position to have a lasting, loving marriage.
