WTF!

I got off work at 8:20 and i was driving home the different way i have been going for the last 3 or 4 times. I am just driving, not that fast and the next thing i know i see lights flashing behind me. There was no where to go but in a shopping center so i stopped. The officer said "did you know that the speed limit is 45 and it drops to 40 here?"  I said "no, i thought it was 45 or 50 and i though i was going 50" He said " You were going 55 and wandering around 58,59 you even have a digital spedometer" I said "I can't read it from the lighting sometimes" He said can i see your license and registration?" I give it to him and he says he'll brb. I talked to my mom on the phone and i was so upset! I wasn't crying, i was just mad! I Wasn't even driving that fast!!!! He came back and i put my head down like i was crying and he came up to the window and said "what would you say if i gave you a waring instead of a 180 dollar ticket?" I said, "That would be great!" with a sob. I said " i think something is wrong with my spedometer" He said, "you might wanna get that checked out." then i said, i need to get my whole car checked out, look at my door handels, they don't even work" "He said, what do you have shoved in there, metal?" i was like,  " I dont know, my dad spent for hours makin it for me." He said thats ghetto!! You need to slow down and drive safe ok? I was like, Thank you !" GOD!!!!!!!
