Most of the replies here kind of miss the point and talk about idioms (hatching eggs, dropping shoes, etc.). Idioms are indeed hard, but every languages has their own. So, when you meet eggs, shoes or whatever in a discussion that was not about chickens or fashion, you can at least suspect it's figurative. Meanwhile, "To fall for someone" is not an idiom but a phrasal verb, and these are (imho) much harder than idioms because they do not "signal" their exceptionality as strongly. How am I supposed to know that "falling for someone" does not involve any actual falling, or that when you "make up with someone" you are not really making anything?
