<em>Hola, Ana Milena: </em>
<em />
<em>Te</em><em> voy a comentar un secreto: mi cuñada y yo </em><em>le</em><em> estamos preparando a mi esposo una fiesta sorpresa. Tú tienes mucha experiencia en dar fiestas, ¿verdad? Si </em><em>nos </em><em>puedes dar unas ideas a mi cuñada y a mí, estoy segura de que va a ser fabulosa. El cumpleaños de Esteban es el 5 de diciembre. Para ese día, mi amiga Yolanda </em><em>nos</em><em> va a prestar su casa. Tiene una casa enorme en el centro de la ciudad. Está bien para sesenta invitados, ¿no? También pensamos contratar a un grupo musical. ¿</em><em>Les</em><em> debemos pagar un depósito a los músicos? Bueno, ¿</em><em>Me</em><em> puedes contestar las preguntas hoy, por favor? Es que esta semana </em><em>les</em><em> quiero mandar las invitaciones a los invitados. </em>
<em />
<em>Tu amiga, Carolina.</em>
<em />
<em>p. d: </em><em>Le</em><em> voy a dar un regalo muy especial a Esteban: ¡un automóvil nuevo!</em>

We need to fill in the blank with the correct indirect object pronoun. An Indirect Object Pronoun is a person that, in indirect way, takes the action of a verb. So this tells us<em> to whom</em> or <em>for whom</em> an action is done. So let's analyze each blank:
(1) Te - Here the action is being performed <em>for Ana Milena, </em>and since the letter is addressed to her, then we use te that is the indirect object pronoun for the second person singular (informal you)
(2) le - Here the action is being performed <em>for my husband, </em>that is <em>for him, </em>so we use le, which is the indirect object pronoun for the third person singular
(3) Nos - Here the action is being performed <em>for my sister-in-law and me, </em>so we use nos, which is the indirect object pronoun for the first person plural
(4) Nos - Here the action is being performed <em>for us, </em>so we use nos
(5) Les - Here the action is being performed <em>for the musicians, </em>that is, for then,<em> </em>so we use les that is the indirect object pronoun for the third person plural.
(6) Me - Here the action is being performed <em>for me, </em>so we use me that is the indirect object pronoun for the first person singular.
(7) Les - Here the action is being performed <em>for the guests, </em>that is <em>for them </em>so we also use les here.
(8) Le - Here the action is being performed <em>for Esteban, </em>that is <em>for him </em>so we also use le here.
