I love my neighbor Gladys, who just suggested that we build a lighthouse. I have the perfect spot to build it at, and then Isabelle tells me that it is a holiday and that I should take the day off! Rather hypocritical of her seeing as she works 24/7! My lighthouse! Noooo! Might tt after I get the bug off bug set items that I want.
Joan shows up on every Sundays before 12 PM no matter what you do.
And turnips only rot if you go BACK in time.
So when you buy them on a sunday, you should only move foward ONE DAY AT THE TIME...and never go back, its a tougher russian roulette but its not nearly as bad as people say.
Do they at least ask for favors? I talked to a villager a thousand times (he was inside his house so he wasn't talking about the bug-off) but still he didn't ask me for anything.
