If I may offer my thoughts.
We are in the early hours of an exciting day in Mineral Town. A new farmer has arrived, and I imagine the townsfolk are overjoyed to have the farm working again, as well as have a new resident. I'm sure we are all still excited to be diving into this new roleplay, so I think this first day is the perfect excuse for all of us to take advantage of our character's enthusiasm, and get to know our fellow roleplayers and their characters. Ending the day so soon could affect our efforts and abruptly end the interactions some characters are currently seeking or engaged in.
Personally, I think this first day is a swell opportunity for us to experiment and get some knowledge under our belts. When the day eventually passes and our characters excitement over meeting the new farmer has passed, they will likely behave in a more "normal" fashion, and it will take time and consideration for some of us to define what "normalcy" is for our creations. Then there is the factor of determining how all the townsfolk feel about one another, and that requires some familiarity.
Heck, just by messing about, I now know I can pester Alex frequently due to his housewife/butler comment. Have fun with that you poor soul.
However, moving forward in the day, such as the afternoon, may be an option worth considering soon, so tired characters (Leon, Lyra, Alex, and Nuka) can get energized and jump back in.
