Would a 12 year old talk about problems with an American provider while training?
I don't think so.
Maybe not 12 in physical years!
However, the behaviour, aggression, inability to take criticism and general teddy/cart petulance do not strike me as someone of maturity.
GATZY, if you cannot accept that your style of English is very difficult to read and if you cannot accept that insulting moderators and other ppruners is unacceptable behaviour, then please consider how you will get on in a multi-crew environment.
