When my grandfather was sick before he died, i was mostly the one with him the whole time. During that time, a few very awkward situations occurred, because he was a difficult man to deal with, and i'm not a particularly skillful person in dealing with people, but they unexpectedly made both of us laugh.
The most awkward of those was one day he was trying to tell me something that i couldn't make out as he was struggling to talk clearly. I kept indicating that i couldn't understand what he was saying, and it got ridiculous. After 6 or 7 times of him trying to be more clear and me failing to understand, i was feeling pressure watching him struggle and getting angry, and getting particularly frustrated with me for not catching what he wanted to say. I kept hearing something in particular but i wasn't sure. It was basically that he was asking me to call my father and tell him to do something in the case that he died. I was hesitant to ask him if that's what he wanted, but i finally gave in and said it, and it wasn't what he was asking me to do. So he smiled and looked at me like i was an idiot, and shook his head to indicate that this is not what he was trying to say. My face got red and i started involuntarily giggling and apologizing repeatedly and then asked him to try again and tell me what he wanted, hoping that this moment can just go away.
I understood after a few times and did what he wanted, and then we started just hanging about again. After a while, he asked me a short question, which i couldn't make out. So i asked him to say it again, and this time he was really agitated, and putting more effort than he should to try and make his words clear. It sounded like he was asking me if i was gonna miss him once he was gone, but i was too unsure and after what had just happened it seemed crazy to even dare and answer that until i was sure. I thought that it made sense for him to say that, given that the tension was sort of broken about the subject, but it still seemed too risky to take the chance and answer. So i just kept shaking my head to indicate that i can't understand, and my decision was to maintain that position no matter what, or ask him to just forget about it (but he usually didn't take kindly to that). After a few more times of him suffering like that i couldn't hold on any longer and just took the risk, and answered and said that of course i was gonna miss him after he was gone, and that wasn't what he was saying.
He laughed and closed his eyes, then raised his hand and looked up and said somethings which seemed like he was praying for god to do bad things to me, and i was just hysterical at that point, extremely embarrassed and ashamed, laughing with no restraint and apologizing for a million times and begging him to just forget about it and tell me what he wanted.
but that didn't work so I asked a knock knock joke instead:
