The context of the following conversation is Jan refused to drink anything but soda and Jan Addison knew this was unhealthy, so she made Jan drink water.:
Jan says Hey, I really am quite thirsty right now. If only I could have soda..
The friend responds I know, we ran a few miles today. Here, I'll go in the store and get you some..
Jan responds I can't, Addison said I can only drink water..
The friend responds No kidding, is there any reason why I shouldn't buy you this fresh soda right now?.
Jan responds It's for health reasons, I was becoming way too dependent on it..
The friend responds Yeah, at least you're cutting down on the sugars..
