 It's just like the need to get another creature up and down in the elevators. And oh my gosh, I forgot the diaper bag back up. It seems like a tiny transaction cost. It's a minute, right? Maybe another minute of waiting for the elevator. But psychologically, it's actually a huge transaction cost. And it makes it way more unpleasant. It also makes more unpleasant that you can't go to greenery unless you physically escort your child and stay there and watch them.
