He could be having a hard time too because you are having a hard time and "displaying" that? I still remember in 8th grade when our science teacher did an experiment with a guy who was late to class one day; he kept telling the guy, every so often, that he didn't look well, was he sure he felt well? and stuff like that and, eventually, guess what? The guy didn't feel well and left to go to the nurse.

If you are considering changing T's at some point you would have to tell this one, I'd do it this next time, get blunt and tell him, "I'm thinking of trying a different T, I can't figure out why it feels like I don't trust/want to trust you?" Then, listen to what he has to say and then ask him about your father, something like, "what do you think about my father?" and see if he mentions he's dead and that the anniversary is coming up (I'm presuming that you have told him when he died and how big a deal it is for you?). If you realize you really haven't said much about your father as you thought, that you have left it to this T to "guess" or haven't wanted to tell him, etc. then explore that particular issue rather than your father and his death per se.

It could be this T somehow does/does not remind you of your father or someone else you don't/didn't like and you could have an interesting breakthrough about trust and talking to people who remind you of others. You have only seen this guy twice so having such a strong reaction to him seems kind of odd; yes, it's nice when we like people right off but we can often learn more from "mistakes" than from everything going how we want/expect?
