It does? I've never seen someone called Tino before.
I'll say it does get confusing though. A lot of people use "Tina" (which is short for my post-adoption legal name too, though only for spelling) and so when there's a "message for Tina" or "order up, Tina" when a food order is ready, everyone who is there stands up. Doesn't help that not only is there a Celestina (my birth mom), a Valentina (me, hence also being "Leni" to some people), and a Christina (the sweet kid who imprinted with me, like pseudomom status), but also a Clementina (grandmother) and an Augustina (great grandmother) and it was a pain, for example, sorting through paperwork when my maternal grandfather passed.
Some more than others.
Had a friend with a classmate named Anakin and he's still in all the school memes post-grad.
