So throw away cause I dont need the fight if she finds out.  

My sister is a single mother.  She has two kids.  She dated drug addicts and got kids and debt.  

We all try and help her out as much as we can.  I am out of work and I end up watching her kids from time to time.  It's not to bad it's usually only on days when one of the kids is sick.  

Sometimes it ends up though that we have to watch both til she is done work.  She has to walk about 20 blocks.  

I have no issue with any of this.  What I have an issue is she will stop and play a video game during her walk home.  She can make this walk in 30 mins more or less when she has the kids with her.  Alone she can be closer to 2 hrs.  I can see her playing cause I play the game to.   

I call her out on it every time in front of the family.  She grumbles but I am not nasty more reminding her of her priorities.  I feel bad for it but at the same time I shouldn't have to watch her kids extra time so she can play a game.  

Am I the asshole
