I hid from the cops by hiding under the bridge.
How come you are hiding from the cops?
Because I wasn't happy with my life. I was desperate, I had nowhere to go
Hiding from the authorities would just create more problems for you. If you did something wrong it is best to turn yourself in and try to fix it. There are always ways to turn your life around.
Nah, I'm just going to stay here and not do anything.
You can't hide under a bridge for the rest of your life. Things will be better if you go to the police and get everything sorted out.
