I am just done with all this drama with his mother . We are the only ones in the family who are any good to her and she does this to us all the time . I told Joe I m not going out there again , and that if I do nt go , Nina does nt go . Joe said he would discuss this with me when I was more rational .

Based on the preceding passage, answer the following question What may be the reason for him not wanting to discuss things now ?
He does n't believe she is thinking clearly .
