At the beginning I definitely felt sad whenever I decided to replace one of my villagers. It was tough since there was a fair amount of emotional attachment to them, and I definitely would've preferred keeping all 10 of my original villagers if it wasn't for the fact I didn't have a snooty as part of that 10, which meant I had to replace one of my original 10 no matter what. It definitely cut deep at the beginning and I felt regret over letting any of my villagers go, but it's definitely a lot easier these days. I still don't like seeing them go as I still grow somewhat attached to them, but since I've replaced my villagers 13 times now, it's now just part of the never ending cycle of keeping my villagers fresh.
