För att glömma vad?
(I couldn't resist myself to google the quote in swedish and continue)
Does "dricker" sometimes imply drinking alcohol as "drink" does in English? If someone asked me "why do you drink?" in English I would assume they were talking about alcohol.
Wherefore literally means "why" (as in: "Romeo, why are you a Montague?" rather than "Romeo, where have you gone?")
Varför sounds like the dutch "Waar Voor" means what for :p its weird to hear something so usual in a differnet way " even though what for can be used as why so its simular
