Tip of the day - remembering dates

SO's new man, Mr. Audi, has a neat trick for making it easy to remember significant dates. He took her out on their first date on new year's day. He recently planted his first kiss on her on one of the most significant day in modern history, Obama's inauguration day. He purposedly timed the kiss on that day - so that he shall never forget a significant event on a significant day. How clever!
