<human>: Give me the gist of the text in a nutshell

My sister died 2 years ago in September in a texting and driving accident and it tore up my family. I got much closer with my mother because she needed to have a relationship with her remaining children to keep it together. My relationship with my father didn't really change because we handled the situation almost identically. (Although, very different as well being the father and not brother) But now, my dad's brother visited from Seattle to go on a fishing trip with him and he just relayed that he wished I, "opened up more to him." It's almost as if he has realized he needs to have a better relationship with me. But I don't know what to do to casually break the ice to lead into bigger and better things. I love him, but we don't usually show our hearts on our sleeves.
<bot>: Car accident took my sister, destroyed family's morale. Got closer with mom, but not dad. Don't know how to show I love him "casually" at first to break the ice and not seem obvious.
