It’s funny how the word “like” can completely change meanings simply by repeating the word, e.g.:
Girl: Sven is a nice guy – I like him.
Girl’s friend: Okay, you like him. But do you like like him?
Girl: I think I do! At first I just liked him, but after seeing him lead the squash team to victory, my feelings have totally changed!
I think that is the only word where this rule applies, and for good reason…
Doctor: The test results are back. I’m sorry—it’s terminal.
Patient: Phew! You really had me worried there, doc!
Doctor: No, you misunderstand. It’s terminal terminal.
Patient: Dear lord!!
