The Mappleton woman always has a big grin on her face almost like Fanny Flasher, in this household she is not so much liked.It always amazes me just how hilarious people think they are. I watched that video...forgot the name of it, Mappleton or something like that, and the MAN started forced laughing before they even started! He giggled throughout! Amazing. And people laugh throughout so many of the videos that I watch. I wish they'd just get on with the talking and stop the giggles!!!
In videos and real life it's insecurity and the want to be positive and be loved I think that's makes people react like this.
But I noticed this in books too. I don't know if it's a translation thing. Before buying a book, I always try to take a look inside. If the protagonists in the book are almost every time answering/nodding giggling, laughing, grinning it annoys me and I don't buy the book. Have nothing against looking on the bright side of life but always grinning, not normal IMO.
