I always thought that the kids looked to be a bit young going around the town with a newspaper and then I realized that I can set what ages I want the service sims to be as well and decided to make the newspaper boy/girl into a teen instead.

Do yall have any preferences of ages when it comes to service sims etc?

Not really, in fact I pretty much completely ignore the service sims and have set them to never age. I don't even really see the newspaper deliverers most of the time because my sims are busy doing something else.

I'm thinking about having one household adopt the paper girl though—she's cute now and grows up to be a beautiful sim, and this town could use more good genetics.
