I'm not going home to help my mom
Why would you not help your mom?
I want to go to my friend's house, get drunk, and get home at 2AM.
The desire to hang out with your friend and get drunk is understandable. That said, you are part of a family and you should be there for your mom. It's important to be responsible before having fun.
I'm going to get a beer. Fuck it, I deserve it.
It's okay for you to hang out and have a beer. However, you should show up to help your mom first. This will ensure that you don't have regrets later.
