Verb conjugation of "excite" in English

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.
Are you currently buried in a lot of work? I am not, because the financial crisis has put me back on hold. I do not work, so I have time for going out in the evening and being online.
