I've noticed an increase in villagers coming up to me 5 minutes before they are supposed to visit my house, saying they have to cancel. What's up with that?
Same for me. I always forget since I really enjoy talking to my villagers, even when guests are over. To be honest, them cancelling is fine by me. I much prefer instant visits than making appointments.
Heh. Guys, tip for you: If a villager sets an appointment to go to their house at X time, and you miss that time, don't talk to them until you find them in their house again. They'll comment on your lateness, but at least they won't get mad.
I'm fine with the appointments, but what's annoying as crud is when you're doing stuff in your house and they just barge in on you. Seriously, who does that?! (Oh that's right, I barge in on villagers' houses... oops...)
