roomates that steal or always want to borrow your stuff

I don't know if this is just me, but when yall got ready for college did you ever worry about having a roomate that might steal or have a bunch of friends coming in and out of the dorm who might do the same? I know there are some of yall out there who know yall got some nice ish (jewelry, kicks, laptops, clothes, etc.) and I wanted to know how yall handled it. Did u buy a safe or what? I ask because I'm about to move into my dorm next semester and I KNOW I got some nice stuff, especially jewelry, and thought about buying a safe to protect it, but I don't want to buy this safe and then have my rommate/other people thinking like "WTH, she think her sh*t too good to leave out!?" I don't want my new roomate to think I automatically think she's going to steal.....any advice? Please and thanks in advance

^^^^Good luck ladies
