So there is always the dilemma of what to get Dad for his birthday. He doesn't like it when we spend money on him. In fact, I asked him once what he wanted and this was his reply: "Just worship me." He was only sort of joking at the time.
There is one thing I've noticed about him compared to others people's fathers. He always carries a plain white hankie in his pocket. This has always stuck me as such a gentlemen thing to do. So I embroidered his initials on a couple of hankies. Maybe that subtracts the manly gentleness right out of them. I like to think of them as little valentines you carry in your pocket.
PS: I almost titled this post "Hankie Pankie" but decided that might draw another sort of search engine crowd.
