Rick and Morty: My Grandfather is Rick?

I traveled back in time to America, where I have parents and an older sister.
The old man is weak, but he has his moments of brilliance.
My mother admires strength, but also feels sorry for my father.
My older sister has a sharp tongue, but she also often defends herself.
These memories allowed Morty to lie in bed and sleep, preparing for tomorrow...
An old man—Grandpa—appeared...
"Hi Morty, I need you!"
At this moment, Morty finally realized that he had been transported into Rick and Morty!
