Perfect as in "perfect town status" or as in "perfectly happy with how my town is"? I've had perfect town status but I consider my town far from being perfect. Probably never will be either since I can never make it look as pretty as others do. ^_^'
My villagers "never want to leave," according to Isabelle, even though they keep trying to move away. So, yes, I have a perfect town status. Truth is, I am very happy with my town. It may not truly be "perfect," but I love how it looks.
My main town was perfect for ages, but has probably lost PT status because I keep leaving junk lying around all over the place (haha, just like me in real life).
My secondary town only has a couple of PWPs, so doesn't qualify yet. I'm trying to figure out exactly where I want everything to go, it's pretty painstaking.
