Ignorant morons please park in my spot

So I have two parking spots, I always park either in between or over so my guy neighbors and I have space to park.  Usually my other neighbors will park closer to the other spot line, but I was not happy to see someone parked in my spot since I was planning on going somewhere later.  Also I hoped no one was in the passenger side.  They have plenty of visitor parking behind them to use and really I think its rude to just park there without asking especially since I barely would of been able to get in my door.  I should of had them towed away or called the cops! Idiots!
