Why does my mom keep forcing me to include my 6 year old sister?

I'm 13 and my mom keeps making me play with my super bratty and annoying 6 year old sister. I have a PlayStation 3 and I got Minecraft fory birthday. Anytime I try to play, my mom FORCES me to let my sister play. And my sister, in the game, breaks everything and messes it all up! I will spend hours building something and she will come along and break it! I try to explain this to my mom, but she says it's not fair that I get to play and my sister doesn't and she says that either I have to let my sister play, or I can't play. It's not fair because it's MY game and my sister has ADHD and she ruins everything. I miss so badly being an only child and being able to play things by myself and not have a stupid child yelling at me. I hate playing with her and it makes me so mad that my mom can just force me to let her play! I need help.

Why is Minecraft PS4 edition more expensive on disk than it is on the PSN store?

These days physical copies are usually cheaper than digital downloads after a while, so I was wondering if there's a reason that the digital version is cheaper than the disk version?

A friend of mine has the game on disk and it came free with loads of texture packs. Is this a feature of the disk version or does the digital version come with this too?

Is there any difference at all between the two?

How to make a bowl in minecraft ps4 edition?

I've looked everywhere, I've googled. Everything is telling me the combination code for the crafting box, but they don't realise you don't have to manually drag the items in the box on this edition, you just have to have the supplies and you re done. What the heck is going on.

Gaming & Streaming on PC using OBS?

So recently i've been getting back into streaming a lot. I'm usually a PS4 player but about a year or so ago i bought a Gaming PC (about £600-£700) as i wanted to experience that side as well. I played games like DayZ, Arma, Call of Duty, Minecraft etc. Recently i've been wanting to stream these games again.

Minecraft for example i play around about 60 FPS but as soon as I start streaming that drops to about 30 FPS. In my stream it is very laggy at about 10 FPS. This frame drop doesn't show in OBS itself but shows in my streams on twitch. I've tried testing my connection, lowered the bitrate and resolution, tried performance boosters but still shows on my stream to be really laggy and low FPS.

My specs are:
CPU - AMD A10-7700K
GPU - AMD Radeon R7 Graphics
8GB Ram

I'm asking (and wondering) if anyone else has a solution to help me before i spend money on buying a new parts.
