About a sentence in a film Idk if anyone here has watched the film "We bought a zoo", it's a story about a man who lost his wife and accidentally bought a zoo because he wanted to change the living environment for his kids (he was wanting to buy a house but that house was a part of a zoo)..., so after hearing the news that he had bought a zoo, his older brother discussed this with him and in their conversation here's what they say that confused me... (His brother wanted to change his mind) Brother: Travel the stages of grief yet, stop just before zebras get involved. Him: It's only two zebras. Brother: Uh-huh Him: And a lion, and a jaguar. Does his brother use "zebras" to represent the whole "zoo buying" thing? or is it a slang expression? I haven't found much useful information. Thanks in advance.
