My friend, A, emailed me and suggested this:
Thadeus, you can then call him Thady for short… It means heart though, might be both a pro and a con. Sending you a hug, A
Of course, I could immediately hear Him saying “Thady” in an effeminate voice and being ridiculous, and making us both laugh like 12 year olds. Totally made me smile. And I love the meaning. 🙂
