A: The so-called grammar refers to the language rules summarized by people according to their own language habits. If many people say this and everyone knows what it means, then sentences that do not conform to the original grammatical rules will become a language phenomenon and be accepted and explained by grammarians. It is reasonable that a simple sentence can only have one predicate verb (the main clause of the previous sentence should be come, and the latter see is either the infinitive to see, or they are connected by the coordinate conjunction and to form a coordinate predicate. Meet sb. Do sth. (Watch me live) Grammatical.
However, we can't say that there is a grammatical error in this sentence, because in modern English, come see and go see have been incorporated into the language system as language rules. Say it is a spoken expression, and the ellipsis is is = to see = to see.
Coupled with the poetic style, it is not bound by traditional grammar. Like finding your life, it's the language of poetry, don't you understand? That's poetry!
