I'm thinking of using my moms credit card to pay for an Uber to get to school
I don't know if you should. Do you have her permission to use it?
No i didn't and I'm sure she would never know. If she asks I'll return the money.
You shouldn't use her credit card without permission. Using people's things without permission is akin to stealing and that's extremely wrong to do. Just ask her if you can use her card or pay for the Uber yourself.
Fuck off, I do what i want. Nobody stop me.
I don't see a need for this level of hostility. Just be aware that you're mother will likely be very upset when she finds the charge on her account. She probably will lose a lot of trust in you.
