As "look down" is a phrasal verb, and it isn't clear the meaning, allow me to ask anyone here, which phrase of the following does "kigge ned" fit better? ===> I look down in shame.(physical meaning) I look down on the future in order to invest. I look down on your "Justin Biever" T-shirt because I don't like him (figurative). Be nice...tak!!!
"Kigge ned" fits better with looking down in shame.
"I looked down in shame" = "Jeg kiggede ned i skam"
"Ser" works better with looking down on things (condescension).
"I look down on your "Justin Biever" T-shirt, because I don't like him" = "Jeg ser ned på din Justin Bieber T-shirt, for jeg kan ikke lide ham"
I am however having a bit of trouble with your "I look down on the future in order to invest", since it doesn't make sense to me in English.
