Well, my kids see how much my sweetheart of 32 years and I enjoy each others' company, and they look forward to the delights of the nuptial bed as well. The youngest are 12 and 14 -- the baby was our 20th anniversary present, with a due date that coincided with that auspicious date!
I still pray that the day will come when I can lift up mine eyes to the night sky, and invoke God's favor on descendants who are glorifying Him with their work on the moon, and/or on Mars. Life in Him is great, and the best is yet to come!
Catholicism, too, is advance, not retreating.
