Hmm.

Well. Hello. M'name's Aberforth. I'm the barkeep over at the Hog's Head Inn in Hogsmeade. Pretty simple life. Pour the drinks, clean up some. What can I say. Had a bit of a run-in with the Ministry a few years back. Long story. Involves some goats. You probably don't really want to know, which is good, because I really don't want to tell you about it.

Really, that's all there is to know about me. No interesting secrets here. Although maybe you've heard of my brother...

[Typist: Aberforth Dumbledore, Albus's brother. Who was at one point prosecuted for practicing "inappropriate charms on a goat". No. I don't want to know either, for that matter.]
