Thank you for your mail of Jan 19th.
I have really no luck with the schedule, this is the second time
that you come to Germany during my absence.
I arranged already my trip to Japan(and probably to Taiwan)
leaving Düsseldorf on June 4th and coming back on June 20th.
I shall phone you during my next stay in Japan(Feb 20th - Mar 7th)
Thank you and best Regards
