Again, I think it's just a way to 'escape' in a situation that is deemed boring, awkward or a little uncomfortable, the home relationship (Leora and Malia) is becoming a little stretched now, they seem to be drifting apart with even a minor argument the other day, no more little parties in the living room, it's just rare, very quiet small talk, phones for an hour, eat, phones for an hour, watch the TV while on their phones, go to the bedroom for more tablet/phone use, maybe put on a show for 10-20 mins to keep the views up, then phones before bed, then another 2 hours of phone in bed while waiting to get tired enough to fall asleep with a few toilet breaks in-between for calls they don't want anyone to hear.
I'm not seeing two best friends here, I'm watching two women who know each other passing the time that they have to be in the apartment by browsing the internet and chatting with people that are not each other and occasionally put on a show to keep the money coming in.
I keep repeating this, but the girls haven't been drunk in the apartment for ages, they seem to have a lot of fun when doing it and they actually look like good friends, they did it a few times when Malia first moved in and both seemed a bit happier, maybe we need more of that?
