Should I still let my sister play with my new Ps5 when she's around?

Hello dear community (well more or less, let's just say somewhere in between),

I pre-ordered the Ps5 and sold my old Ps4.

My sister also has a Ps4. After I sold my Ps4 I didn't have it anymore to gamble and she didn't want me to play with her Ps4.

I was only allowed to be there when I lent her a game. She didn't even want to let me play with the Ps4 for a very short time.

When I asked her why she did that, she said she didn't know.

I should also say that we always put ourselves down, so for fun, but that she doesn't let me play with the Ps4 was really exaggerated, even with my game.

Whenever there's something special I would invite her straight to me, but with her without new things I don't even get into the room.

Should i do the same to her?

We don't have beef or anything.

What do you all mean?

I think this has something to do with teraflops.

Just because your sister is like that doesn't mean you have to act like her. Do what you think is right, even if you don't get anything in return.
