This is a paragraph from one of Wodehouse's books.
Nephew(also the narrator):"Golly!"
Aunt:"You may well say 'Golly!' Anatole, God's gift tothe gastric juices, gone like the dew off the petal of a rose, all through your idiocy. Perhaps you understand now why I want you to go and jump in that pond. I might have known that some hideous disaster would strike this house like a thunderbolt if once you wriggled your way into it and started trying to be clever."
Harsh words, of course, as from aunt to nephew, but I bore her no resentment. No doubt, if you looked at it from a certain angle, Bertram might be considered to have made something of a floater.
What does the phrase as from mean? Does it mean some kind of emphasis? Or are there any implied words which are not present directly, e.g. as (seen) from? Please give me some examples from the Internet of similar usage. Thank you.
