Re: Leaving the Dojo
1. Is leaving his old sensei justifiable?
I agree with John.Everyone will do what they feel is best, I do not think it needs to be justified by others looking in from outside. If he feels he should leave, it is probably best so.
2. Should he approach his old sensei and tell him the truth or leave and tell lies about the real reason for his leaving?
It will be difficult to do it, but it is much better to tell him and be upfront with why.
3. Can he do his resignation in writing or better personal?
It is better in person... but if it is difficult, writing will do.
