I have 10+ parking tickets that I've never paid.
Oh dear! Why are you letting them pile up like that?
Because I'm too embarrassed about them.
You really should pay your parking tickets. It's wrong not to pay them like that. Pay them or you could go to jail.
It's too expensive to pay them all at once.
If you can't afford to pay them all at once, talk to someone about setting up a payment plan to be able to pay them off. If you just ignore the tickets, things will only get worse with more fines and maybe even jail time. If you show that you are willing to work to pay them off, they will likely work with you to find a payment plan that works for you.
