it wasn't really in a bad thread or anything, it was just the main /b/ page, and I hadn't ever used vista before, and I exxed out, but it didn't kill the tab, so my grampa goes on to show me something, and opens up firefox, and BAM, 4chan. I was like aw [cabbage], exxed out again, then went ctrl+t and exxed out of the 4chan window. I got scared [cabbage]less, cause he was old, and like, it was /b/ and I'm pretty sure there was a picture of a naked girl there. So he might have noticed, and just decided to ignore it, or had no idea what was going on. Hopefully it was the latter.
