If you've ever opened a greeting card and smiled at the endearment inside, you know they make others feel the same. For those special occasions, visit a good card shop, buy 2-3 from each of multiple categories, and file them in a holder on your desk. Put USPS Forever stamps on the envelopes. When someone's birthday or anniversary comes to mind (or comes up in conversation), pull the correct card from your stash and fill it out. Easy-smeasy, job done!
