Half of the Conversation

I think the thing that probably frustrates me most about Mr. P is his inability to hear/retain more than half of what I say to him. He always is claiming I didn’t tell him something, even though I know I did–usually multiple times, but he just didn’t hear or listen to me.

I’m pretty sure that when I open my mouth, he tunes in and out like he would to background noise coming from the TV.  I haven’t figured out how to solve the problem. I have figured out that it’s about 50% of the information that he does hear. I just never know which 50%.
