My brother in Hydaelyn, do yourself a favor. Go outside. Get off of your computer. Log off, take a break, do some house chores or something. How your neighbors choose to decorate their FC is not and should not be the end or the world. If how someone decorates their own space that they paid for is bothering you this much it's time to go get some fresh air.

Also be thankful they aren't the sort to spite you by lining their yard with Namazu Effigies.
