Completely agree with cellphones being used excessively, to a point.
Sims in TS4 have always been obsessed with their phones. I hate the idle time they spend on it, and I have Mods which have stopped all phone use for all ages, which I have used for years. The current one is (No Auto Play on Phones by MSQSIMS on TSR) - But. With High School Years, I added a Mod that ONLY lets Teens be obsessed with their phones. (Phone Animation Teens Only by MissyHissy) - I think they do go a little bit overboard with their phones, as they literally walk into walls at school while they're on it... but with Social Bunny, I guess that is to be expected. XD
