Knowing the basics of many languages will help save you from embarrassment.  Know some English, French, Spanish, and Chinese.  Otherwise, you may interpret something completely different...much to your own chagrin...

Example:
"Okie dokie!  Would you like me to meet you there?  Or meeting me at mi casa and go together?"

[You, having next to no knowledge of Spanish, think that "Mi Casa" is a Vietnamese noodle place called "Casa"] "Where is mi casa again?"

"Mi casa = my house in spanish."
