My brother in law has ADHD. He lives next door to me.
He has a car he parks on the street. In my city you're required to get a registration sticker for your car, it's like $100 or something, good for a year. Every day you don't have a valid sticker you can get a new ticket on your car. It takes two minutes to go online and order a new one.
For the last three years, hes been racking up tickets on his car for an expired sticker. One a week roughly, $60 per ticket I think. He usually lets them pile up until he gets final notices then pays them all online at double the cost.
Twice now he's has his car booted, then impounded, due to unpaid tickets. He even includes tickets on his car as part of budgeting. I've offered a couple times if he'd hand me his license to go online and order the sticker for him. I've stopped offering since that offer is met with intense anger.
It takes TWO MINUTES to go online and order a new one. Poor guy
I did something like this once. I was meeting a friend at a bar and she was with another guy I never met. I had just moved back to the US from Germany, so she introduced me and said "he just moved here from Germany," not realizing that it wasn't clear I was American. So he starts asking me how I like it here etc, and I threw on a German accent and went with it (I speak some German too). I pretended that my English was a bit rough but could get by.
We hung out for like two hours and then when I got ready to leave I dropped the accent and said in my normal Midwestern American voice "Ok cool to hang with you bro imma head out," and left.
