And there are other events like Mike telling Kylie he wanted to let some time pass before calling her even though you can call her that same day she gave you her number if you raise your stats accordingly.The whole idea behind it is that the girl notices you going to the gym often, or at least renewing your membership, then working out. Similarly, there's plenty of events for other girls where you need to wait 2 or 3 days, sometimes even multiple weeks.
It's my effin money, if I want to waste it by buying another gym membership unnecessarily, then so be it! Especially when that same gym is running in the red and is desperate for capital.
