But you do not want to discuss Kevin's more relevant points? I'm interested much in this discussion and would like it if you continued.

Kevin didn't answer to Hugo's more relevant points either (the interface reference was a BTW in Hugo's answer to Kevin) - so maybe it's contagiuos.
I'm pretty sure Hugo would share his "use of interfaces" knowledge/opinion with you if you asked, no need to call on Hugo to elaborate on Kevin's points relevant or not.
