Si quieres describir tu situación con un poco de humor di que eres un 'soltero de oro', que es algo así como un Don Juan.

jajajaja un solterón en España es una persona que no 'se come un rosco', que está solo por mucho que lo intente. Es una palabra que en el pasado tuvo connotaciones muy negativas para la mujer. Cuando una mujer se hacía mayor y no se casaba, muy difícilmente podía cambiar su situación. Solía decirse que era una 'solterona' o que 'se quedaba para vestir santos'. Pero vamos, hoy día poca gente se enfadaría si se lo llamaras. Espero haberte ayudado, ¡Un saludo!

Hello Derek! 1. Dame los libros que te sobren & Dame los libros que te sobran. Questions: A. Are these two sentences have the exact same meaning? Not exactly. The first one refers to the books those you have while in the second one you are using a hypotetic case. "If you have books left over, give me them" -> "Si te sobran libros dámelos" "Dame los libros que te sobren (si te sobran 'if they are left over')" Also it could be a kind of future: 'Give me the books left over those you will have'. B. Is there a difference on the things that each sentence emphasizes on? There are books in some, but in the second one the transmitter manifestly does not know which books will be left over. C. The subject in the later half of this sentence is los libros? No. The subject in both are "you". We don't mention it because in Spanish is very common to use the 'omitted subject'. D. So the usage of sobrar here is similar as the word tocar, when we say someone wins a lottery in Spanish?(le toca la loteria) No. 'Tocar', as you said, means both 'touch' and 'get' (in some contexts). 'Sobrar' is a verb to say when you have something that is left over. "Sobran pupitres en el salón, muchos alumnos no vinieron hoy porque están enfermos." "There are desks left over in the classroom; many students did not come because of illness." E. Why te is used here? What does it called grammatically? 'Te' replaces the indirect object. Is a short way to say 'a ti' ('to you'). Gramatically is a personal pronoun. Is, according to the RAE (Real Academia Española): 1. pron. person. Dative or accusative form of 2nd singular masculine and feminine person. It does not support preposition and when the verb is enclitic it is postponed to the verb.

2. Los estudiantes que van-vayan a la excursión tienen que apuntarse ahora. Which one to choose here? Are the both right? If yes, what is the difference? If no, why? Both are right, but the second one is more accurate. The sentence has subjunctive verb (vayan), something hypothetical, doubtful, possible desired that usually appears in subordinate clauses. (like in your first sentence) "The students whose go to the excursion have to sign in now" -> Is like say "not sign in if you will not go". I hope that I help you! ¡Saludos!
