Ok, guys read this:

According to many native Spanish speakers, the most hated phrase of question in Spanish is ¿Me entiendes? = ¿Tú me entiendes? =¿Entiendes?

Why? Because it seems that you are questioning the IQ of the interlocutor. Therefore, if you really want to sound more sagacious culturally talking or even more understanding of the human psychology, you may want to say instead: ¿Me di a entender? Which in other words may sound like: Did I explain myself well?

People may get offended with the popular phrase:  ¿Me entiendes? = ¿Tú me entiendes? =¿Entiendes?

Though the question is a more cultural-linguistic tendency, deep down, it bothers a little bit.

Well, it seems that learning to speak a language is learning how to better apply its culture.
