recently, i called the new t, and she always returned calls, this time she did not, which i didnt care because i have no relationship set with her yet, but its a part of building a relationship, so i did wonder, because she is consistant with it, so the following morning, she called me apologizing, that the previous day she was in meetings all day. So you should address it, openness and honesty is part of that relationship, whatever bothers you , you should address it, no matter how minimal it is, trust me.
