In the movie Casablanca, Humphrey Bogart (Rick) says the phrase here's to looking at you kid meaning when he toasts his girlfriend Ilsa (Ingrid Bergman). This quote is voted the fifth most memorable line in American cinema and was spoken four times throughout the film.
Rick says the line to Ilsa while drinking alone at a small cafe in Paris, listening to Sam (Dooley Wilson) playing
Here's to looking at you kid meaning is a very common expression in English and is also used when saying goodbye. The phrase is usually shortened to "to" because of American slang that leaves certain prepositions out.
Using a quote like this is a great way to express your feelings for someone in a subtle manner. It is also a great way to say hello to them without revealing anything about yourself.
The origins of this line are a little unclear but it is thought to be improvised by Bogart while he was teaching Ingrid Bergman how to play poker during breaks in the filming process. During one game, Bogart beats the Queen, King and Jack by laying face cards that all appear to be "looking at you."
This is another example of how quotation is an important tool for Rick and Ilsa to use in their relationship. It is a simple way to convey how much they love each other and it is a powerful and effective tool for coping with their heartbreak. It is also a wonderful way to remember the good times they had together.
