I was robbed in Sims 4!

I have a nice little family going. I had hired a nanny at some point yet to my knowledge she/he never showed up to work! Anyways, it was back before my couple had their kids. That a teen, a blonde haired boy that was lanky randomly came to my house. I didn't know who he was cause he never came to the welcome wagon at the start. I think his last name was Sweet. I welcomed him in. I had some kid stuff in my house you know preparing for upcoming parenthood I was planning. He didn't talk with my sims which were young adults after being allowed in. He was casually looking around and I had a giraffe toy standing tall in a corner. Then he went into my study and played on the computer for a while before I told him to leave. It wasn't until later I realized I was robbed. He somehow had taken my giraffe! It was missing from it's corner!

I guess he got it when I was attending to my sims' needs so I couldn't look at him, bam, pocketed my giraffe. And I haven't seen him since then. But I remembered that thief was a job option and stealing things is a trait. So I'm guessing he had the stealing trait. And I've been on alert since then. He hasn't come back so far. But I'm sure he might try again. I plan to get Cowplants to guard my house from future invasions. And I wish I could have caught him stealing my giraffe so I could have the man of the house attack him for being a robber!

Sorry I didn't know where to put this. But I want some help identifying the teen thief if anyone else had a similar experience. And I don't have any screenshots and I can't remember the teen's name. If he can't be identified then I hope this post helps others be aware there might be a blonde male teen npc sim who will pocket something if you let him in. Good luck other simmers!
