Translation of flaunt in German

After next week, I will tutor the Mr. Zillmay from the language lab in Los Angeles, he is currently in the states. The lesson will take place in LA, but it may be held no earlier than mid-February.
I do translate to Spanish, but I always inform the client about my problem, in order not to have any dispute. The corrections I receive after proof reading are mostly a confusion between the different time forms in Spanish.
What are your hobbies? The first year I have been taking swimming lessons. It's great. I am married and I a have a son. We can also speak English if needed. Usually, I like to focus on one language.
