Input: Just 30 min ago I went downstairs to play my piano. I have a big family and I only get a 20min window when I can play my piano with no people downstairs.

I see my uncle, who is currently visiting, on the couch, sleeping. I try to set my piano up quietly, when my dad comes in and wakes him up, to move his car. They both walk outside, so I start playing. I have a concert coming up soon, so I need to practice.

I get halfway into my piece, when my dad and uncle come back and start loudly talking while walking around. I get pissed, turn around and say:

Is it necessary to scream around right now?

My dad quietly says:

No.

And they keep quiet. I keep playing my pieces, when uncle's wife, my aunt comes downstairs with her 3yo. They make much more noise, so I stop playing. They want some ice cream or somethin, so they are trying to get ready. I grab my phone and browse reddit, not playing the piano, right in front of them. They leave, I finish my playing and come back upstairs.

I tell this to my mom and she got angry at me, and that she didn't raise me like this. She said, that now the uncle will be offended and will nag about me telling him to shut up for a long time.

AITA for this?
