Another special day

According to my nifty new calendar, today is "Techies Day." Who knew? Since I was married to one, gave birth to one and am Grandmother to four Techies I guess I'm glad that they have a special day. I also have many friends who are Techies.  Now here's my conundrum - do I tell them all that they have their own special day? If I do, will they expect presents and cake? Should I plan a big Techies party each year? I can see this getting way out of hand. Perhaps I just won't mention it to anyone.
