At first I didn't mind street pass villagers. I didn't even know we could have more than 9 villagers at the beginning and when Sally moved in after I took my 3DS to the mall I was pleasantly surprised. Wolfgang was my second streetpass move in and he was pretty cool.
But then I learned about villager resetting and trading and started getting really serious about who moved into my town. Sucks because I live in Japan and I can always get lots of houses and dream addresses from streetpass so it was fun taking my 3DS out. But no more.
I still accidentally got a few more, and the worst was Nate who moved in from my friend's town when she visited me. I was soo angry to see his green-eyebrowed face! Luckily he moved out pretty quickly!
