Regarding the meeting in early May: I could not reschedule the appointment at my daughter's doctor and I will definitely know if I can come during the first 2 weeks. I guess we should talk next week.
This messaging systems is very weird, especially if you are older than 30 or 40... I do not understand how it works, but it works... once we put a message out, over 2000 people see it within 1 day per page per message.
Do not worry, please, all is well here. I find it fascinating how fast you can write texts in foreign languages. I know how hard it is, and I congratulate you. Waiting to your next email.
