So I have a couple of questions things.
1st: When a villiger doesn't like you/not friends with you do they bow there head instead of waving? Because I swear Egbert bowed his head
2nd: Do moons in ACNL keep in time with really life moons? Because I'm obsessed with moons and I swear they are in time.
1. I never thought about it b4, but i know that they bow
i guess it makes sense, considering waving is more casual for friends and bowing is for people who you arent yet comfortable with
2. I didnt think there was a 4th dimention barrier to real world weather/star patterns.
Time traveling would also screw this up so the answer is likely no
about the bowing heads thing, i think some villagers do it anyways. it might be certain types bow, and others wave. either way i don't think it depends on your friendship.
about the moons, i have no idea tbh but that would be so cool bc i love astronomy c:
Bowing vs waving corresponds to personality; I've no idea about the moon phases, but I've seen other places suggest that it might be (in one particular QR code outfit, actually). I can't check, because I TT.
