I agree with >>460 san.
TO-RU san declared here that he sent mail to Jim-san. You were able to read it. >>269
He believed that it was able to be sent to you. You had the method for the confirmation.
But you nothing but left the problem.
I think that you only had to say to him at that time, "I have not received it".
When seeing from you, TO-RU san or IZUMI san might be dissenters only of inquisitive.
However, they seem always to be making an effort to give necessary information for you and
to talk with you, I think.
I sincerely hope you do the handshake of reconciliation with them.
