This thread reminds me of things my sims never do, like go to a movie or a restaurant. I thought these places are there to buy and earn money from other people who go there :smiley:
So yeah, my sims are mostly outside and talk or play something. That may also be the tables in front of the restaurant, the parking lot of the gym or the space in front of the stadium. The latter place gets bonus points for offering free tours with some additional free public fun. You can even play soccer in the library.
Which reminds me I should probably sell all those flowers my sims never use. My hopes of opening a flower store haven't materialized so far.
