As a child when studying English, I did some really bad mistakes. For instance, when learning the past forms of the verb 'to drink', I would say drink drunk drinken instead of drink drunk drunken. Did you do silly mistakes as well? This questions goes out to everbody, not just people that learn English as a second or third language :=)
Moreover, I have just realised that 'drinken' at least seems to be a correct verb form in Dutch:=)
