Leaving the matrix

I have a cart full to the brim with groceries. I'm standing in front of one of the front entrances to GTA V prison. I know my people are coming after me, so I barricaded the entire entrance with the groceries and with the shopping cart. Some how I have enough and it's completely blocked, but there is a way around and I put it out my head so That they won't think of it. I walk over to the left and decide now is the time for a shower. I get undressed and turn on this random ass shower and take a quick shower. When I'm done I get out and get dressed, and I come to check on the barrier and see my half sister pulling it down and jacking the groceries. I yell at her and she acts like she didn't know it was a bad thing to do. I feel she works with them.
