Verbos como gustar
 Gustar means to please.

person that pleases that is the subject.
 When gustar is followed by one or more verbs in the
infinitive, the singular form of gustar is always used.
 Gustar is often used in the conditional to soften a request.
 Many verbs follow the same pattern (aburrir, caer
bien/mal, disgustar, doler, encantar, faltar, fascinar, hacer
falta, importar, interesar, molestar, preocupar, quedar,
sorprender, apetecer)
 The construction a + [prepositional pronoun] or a + [noun]
