Some months ago I bought a bottle of white wine home. I told my parents I was gonna use it for cooking, cause although I'm of age, they wouldn't stop complaining about it if I just told they I was gonna drink it. So I drunk it the same day I bought it and then filled the empty bottle with water and those alcohol used for cleaning and put it back in the fridge. However, I forgot about it and now my dad told me he just drunk half of it. Is that dangerous? Can that do anything bad to him?
