After your last post where you publicly accused your mentor of missing a scheduled training session, for all of the USA to see, I personally looked into this on your behalf. Again, the advice to be open, honest, and truthful is good advice, yet either there is a significant language barrier or you continue to choose not to accept that good advice.
Since for some reason you want to seem to continue to do this publicly.... I'll go ahead and publish the facts. Your mentor told you a week earlier that due to his existing training schedule, family schedules, holidays, etc., he was not available until some time after 2100 hours on Tuesday the 20th at the earliest, and asked you to please reply with a day and time that would work for you. You never responded until you sent a note around 2000 hours on Tuesday the 20th trying to confirm for 2100. When you are given a week to set up an appointment, and you did not, your mentor, in my opinion quite reasonably, gave up on you. Then you send a note about an hour before you were looking to be trained, but your mentor didn't see the note until after 2100. You called him out for missing a training session, however no training session date and time was agreed upon between the two of you. If you had sent him a note and acknowledged that you were looking for a training session in one hour's time, and acknowledged the fact that it was a long shot hope, that would be reasonable. However, you called him out publicly for missing a training session. Perhaps there is a language barrier, but you need to understand that there was no scheduled training session, and it is completely and totally unreasonable to expect a volunteer to see and react to your no-notice e-mail within an hour. And you were wrong for calling him out publicly for missing a scheduled training session, because there was no scheduled training session.
Calling someone out publicly is indeed poor form and in poor taste. Worse, the facts do not support your position, reflecting badly on you and your judgment. I strongly suggest that you use your discretion in the future and do not take such things public, but try to resolve them one on one, or with the facility leadership.
When you posted your complaint publicly on the forums, I looked into it to try to help you. However, I take great exception to misinformation being published on the forums that attempts to tarnish one of my facilities and/or its members, thus this final post to clear up this misinformation. That said, this thread has run its course.
