Input: The downstairs tenant has a tendency to leave at really late hours at night. She works from home and doesn't really leave the house during the day. Our driveway fits exactly 3 cars, so hers, my car and my mom's. Our town doesn't allow for overnight street parking and will issue you a ticket for doing so. My mom and I pull out our cars during the day so the tenant isn't blocked in (driving to work). This musical cars business happens on a regular basis but the other day especially annoyed me because my mom bends over backwards to accommodate the tenant.  It was 11:00 pm and I wanted to pull in my car. We always try to arrange it so the tenant is in the driveway first cause she doesn't need to get out in the morning. I go outside and see that she has left and her car isn't there. My mom insists that I wait to pull in my car until she's back. This is a weekday and I have to get up at 6:45 the next morning. 1:45 am rolls around and she's still not back. I go outside and pull in my car so she can't park behind me. The next morning I get a passive aggressive note in the mailbox saying "don't block me out of the driveway" from the tenant (she didn't get ticketed from parking on the street that night though). My mom gets mad at me that I did this. Maybe it is a tad petty but I have received $60 worth of overnight parking tickets in the past few months from waiting for the tenant to pull in her car at absurdly late times. Of course I have to pay them. The tenant also gets mad if I knock on her door in the morning to move her car so I can get to work. My mom just says "we have to work around her schedule" because she's paying my mom. I just don't get why I have to work around her abnormal schedule and pay for these parking tickets in the process.  AITA for blocking her in this one time to prove a point?
