This also confused me. In spanish 'me' can be a direct or indirect object. 'a sus padres' can be direct object using the 'personal a' and also the indirect object.
the spanish me means the english me. They present/introduce ME to their parents. In sentences with object pronouns, in this case me, is moved ahead of the verb (presentan). Without the me, the sentence would be "they introduce to their parents"
Ellos = They
me presentan = introduce me
a = to
sus = their (plural because upcoming noun is plural...)
padres = parents
Hope that helps. Theres good object pronoun lessons at http://learnspanish.com (unit 4 in Grammar section)
Still puzzled why "sus padres" couldn't be also translated as "your parents" or "his/her/their parents'?
female speaker always sounds like "ellas" when DL shows "ellos", whether I use speakers or headphones.
Why isn't "They are introducing me to their parents." okay. All the other verbs you don't need: Me están presentando a sus padres.
