Five's A Crowd

I have a teenaged Global Superstar, Rock Star. He graduated from high school early and now he and his siblings are at university, sharing the same dorm. Paparazzi and fans are almost always about. Erik has an Award Show to attend, so I send him to take a Soothing Shower (Practice Makes Perfect Trait). He steps into the shower, but before he can even twirl, four other Sims follow him into the co-ed bathroom. One of the women steps in front of him to block him from the actual shower head. He stands there fully clothed for only a moment and then proceeds to brush his teeth, which is something else I had in his queue.

I found this a bit unusual. I am aware that Sims don't like being walked in upon, but I found this funny, even so.  Also, I've noticed that dorm-life is a bit lax on the walking in on another reaction. These four interlopers were all females. He is only a teen, and I guess rather shy. LOL

What unusual behavior have you witnessed from your Sims?
