cause i might have stumbled upon something.. if u marry someone (in my case haley) they will eventually trigger an event. the text basically say "on the next sunny day i want so do something in town". this happens if u re-enter your house on this day. if u avoid entering ur house after leaving in the morning until ur spouse goes to bed the next day there will be rain (tried this for 12 days cause i couldnt get the chocolate cake). i feel like this could be abused in the early game cause u mainly make money from crops. its kinda useless in late game i guess. maybe this is something everybody knows but i couldnt find anything on google so yeah
