This only happened to my ex stylist (Is now a self employed sculptor) once, one of her clients came to her house. I'm guessing it was because her husband? father? just died (She had the heartbroken/grieving thought bubble) and she wanted comfort, so I indulged her.
My family has just moved to Sunset Valley, it will be interesting to see if they get visitors there although both parents are self employed so I'm not sure they will, lol.
