<human>: My papa passed away on this day years ago. I wanted to tell my mother that I am sorry for her loss as I do every year. I wanted to wait until I had the right moment. I was going to at the end of the night as we would be alone. My sister runs into my room and says that my mother is mad about me forgetting about it. I go to talk to her and explain. Saying that I was waiting until the right moment and she told " I'd rather have you tell me the truth than lie to me." When I told her I wasn't she just said "ok." and went upstairs.

Can you provide a brief overview of the text?
<bot>: Mom is upset because she thinks I forgot the day her father passed away. How do I handle this situation without seeming like I am trying to save my own skin?
