The answer is "Te extraño"

Yup, i guess so. I ask my Mexican friend on MSN, the answer is Te extraño. However, the Spaniard, the anwer is Te echo de menos. Haha. Thank you so much. :D

Significa "Te extraño " que se usa en America Latina.

We use "Te echo de menos" in Spain. Of course we understand "Te extraño" but it is less frequent.

"Te echo de menos" (no "H" as it comes from the verb "echar", not "hacer") is mostly used in Spain, while "Te extraño" is used in Latin America. Both are right, but each of them is typically used in different countries.
