This is kinda weird… Yeah, they can get big. Most usual is to have 4 names (2 first names + mother + father)
Anyway, it’s kinda weird because I wouldn’t give anyone more than first and last name… And that’s what most people do, (unless we’re in the rare situation where two people share the same first + last name). Why was your friend making you write his full name?
Exactly, they’re the same picture, right? /s
