I got them from posts on the Teen Board. The locked in the bathroom tag was a game thread called "Truth" and you had to post a question and the person below had to answer 100% truthful. So i put "has anyone ever locked the bathroom door and then thought you could'nt get out?" and I mentioned that I had done it many a time before

I wanted to see if I was the only one.
And the "bug-free" tag was a thread that was started called "cockroaches" and a girl had mentioned about a cockroach and asked if anyone was afraid of anything. So I posted that I was afraid of almost anything that was a bug.
and then the tag-fairy has linked both stories together in my tags.
