Dad steals my socks?

Hey, I'm Celine (24) and I have the following problem. I've noticed a lot of my socks disappearing but then later reappearing. At first I didn't think anything of it because I'm pretty clueless. The weird thing is that the socks disappear from my wardrobe and then reappear in the laundry basket even though I definitely haven't worn them. Hmm. It happened again recently. I wanted to put on my white Nike sneaker socks that I had definitely put in my wardrobe the day before, but they were no longer there and were back in the laundry basket. When I wanted to take them out, I noticed that the front and the toes were completely wet. Can anyone help me? P.S. I live with my dad. Best wishes, Celine
