Mazan4: Rainer please let me know if that is ok with you and I will send you a round trip ticket.
Wow, that's absolutely amazing, Mazan4, and of course highly appreciated! The only problem is that the THM date is not yet fixed, so it is not possible to book a flight from Düsseldorf or Frankfurt to Toronto and back. Oh, and I would also have to ask my employer for an entitlement for vacation. Anyway, we'll get that sorted out.
Thanks a lot for your generous offer!
