Hang out at your sleep spot 24/7 with your windows and doors open
Ask anyone you meet if they have an painkillers for them
Make the area around you stink by pouring pee out your window over and over again in the same spot
Yell at your boyfriend multiple times. Park your second car perpendicularly to your first car so you make an L shape and your second car is jutting out into the roadway where people drive
This is what my “neighboring” free-sleepers did. I had been sleeping in the same spot for MONTHS with no problems but they lasted one week and got me ousted too.
