*me, practicing piano, and getting tired of it*

Grandma: "Do Autumn Leaves."
Me: "I'm really not in the mood for that right now, I'm tired."
Grandma: "Okay, do it anyway."
Me: "..."
Grandma: *singing part of it in a voice that bugs me*
Me: "Please don't do that."
Grandma: "Sense of humor?"
Me: "It bothers me."
Grandma: *does it anyway*

Later...

Me: "I really think I'm music-ed out right now." (Aka im so tired of playing that i cant play anything without making 100000 mistakes)
Grandma: "Okay. You can do it." *makes me play it again*

And she wonders why I'm in a bad mood all the time.
