Yes, it's my mom's dad, PK.
The thing is, he's hammered me over the head to get sober all throughout my 20's and early 30's, you know? And so I finally did. And now when we call him to talk on the phone, he's evasive and has quit asking us to come visit. We ask when he'd like to get together (that means go there, because he's never come to my house and will never do it), and he keeps putting it off. For over a year now. So I know without a doubt, he does not want me there, and it happened suddenly.
