I kind of forgot about it during the day yesterday, because I had a real shit day at work, and I was telling him I was in a crappy mood. He was like, yeah, I am too, it's the anniversary of dad's death. I felt like a complete ass.
I stayed the night with him, and he mentioned several times that he appreciated it and was really glad I was there. And he said he talked to his dad about me when he stopped by the gravesite.
