Someone posted earlier that you need to get the milk, give it to her, then give her the coke, then give her the rum...I have tried every combination of that...milk / no milk...rum / no rum...coke / no coke...milk with coke then rum...milk without coke then rum...rum only...milk only...coke only...rum then coke milk the next day - it does not work.
I'm sure there is a combination or sequence that works, although I'll be damned if I can figure it out. I have neither the time nor the inclination to spend so much time progressing what should be a simple task in the game.
If someone would like to provide the actual sequence with details, it would help those of us that are struggling.
