A couple of interesting posts from L&P from 2 years ago.
So, it would seem L&P either underestimated just how much would be needed or the game has simply become bigger than they anticipated. In any case, we're at that "2-3 more years" stage now, and so unless L&P has been planning to cut down the number of events per day in order to produce full day updates every few months, this game will likely take up to 10 years if development stays at the same level it is currently at.
So basically, if you're not doing the Sophia/Ellie, Sophia/Dylan, and Sophia/Patricia content, then you're missing out.
The Ellie/Julia event, or the yoga event, which one will it be? Personally, I'd say it's the Ellie/Julia event because I doubt Sophia will do anything will Claire or Marie, and whilst she could do something with Patricia, I don't think she's quite ready for that yet. Ellie and Julia are young and would be more willing to do something like that whilst Sophia still has her hang-ups.
