Patron Saint of Engineers?

OK, so there's a title St. Patrick has I didn't know about until earlier today, when minutiae about his various patronages were shared by a friend. I knew he was the patron saint of Boston, but not of Nigeria; this engineer thing was likewise a revelation to me. I managed to celebrate the day quietly without green beer or cabbage, but with corned beef & mashed potatoes for supper after my Bible study gathering at church. I also received early birthday gifts in the form of flowers & Lindt truffles from hubby, who'll be working late tomorrow evening to make up for his being at home tonight to help me out with the children. (I suspect I may be as well, catching up on paperwork for my job!)
