Because he loves you!!!! HE CAN'T LET YOU GO!!!!!!! He's « lame turnip » for you!!!
Before you say, that COULD be a reason, you never know.
Well, if you try to leave at night, he says it frightening,scary and dangerous because you have to past mountains (Aaah, pumas!) and how's he know we haven't finished our work? Has he been........... spying on us?! How dare he >:|
Yeah, it leads right up to Mineral Town. How do I know? Go up to the villagers on a wednesday (Any wednesday, they do it every week every season every year etc unless it's on a festival) and they'll be heading out to the farm way and talk to anyone of them and they'll say they're going to Mineral Town~Mostly to shop.
But, in the day, I don't think we'll ever know why he won't let us go to mineral town. Maybe he knows something we don't?
Jackie: Wait! *Insert name here* your work is not done yet! Blah blah blah..
You: « What The Eggplant »?! I've married, my kid is up to teenager and I am friends with EVERYONE in the valley, I've married the HG and gotten all 101 sprites. I've got every fish known to mankind, there's literally no fish whatsoever anywhere in FMNV because fished 'em all! ALL my livestocks are at the highest level~same with my tools and buildings~and have won ALL the contests they enter! Every square patch of hoeable land is tilled and has 100lv crops, I have seen just about ALL random and heart events available to watch, all my animals and spouse and kid have the most hearts possible, I have got down to the bottom of ALL 4 mines, connected GBA, have everyone else at red, had all the normal marriage candidates marry their rivals kind of thing, made every type of food AND have 99 of them each. Plus, lets not forget that I unlocked the waterfall to which I also planted 100lv crops EVERYWHERE in. All my buildings and pond are made out of Gold Lumber, including my fences, I have an incredibly large fodder field, I have every kind of tree, My name, my kid's name and my farm's names are THE BEST NAMES IN THE WORLD and basically I've practically done everything. I'M DONE WITH WORK! So why won't you let me pass?
Jackie: Umm, well you see.... Err.. I can't answer that..
You: Then get out of the way! I'm going with the rest! I'll be fine.
Jackie: *Gives sad eyes* Please don't, I'll be lonely.
You: YOU HAVE THE OTHER SPRITES!!!!
Jackie: But... But...... They don't understand me like you do. I-I-I LOVE YOU!!!
You: *Steps away* Keep away from me, I'll be back.. *Runs off*
Jackie: *Grins* Hehe, now I gotta think of another excuse *Vanishes*
Well, MT is slightly like a 'city' Sometimes people do call things, like towns, cities when they're not...
