My household is comprised of six individuals; four are female and two are male. There is one debate that seems to be a constant argument in my house. We  discuss this issue, at least,  once a month and have never reached a consensus.  As one might expect we split right along gender lines.

So I have decided to throw this question out to the blogosphere. Perhaps Gotham can help  my family achieve harmony on this issue. The toilet seat, up or down? And, most importantly, why?
