h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

My sister seems to have a few problems. She insists on drinking tea with cups full of sugar dumped on... Every morning, day, and night. She has obsessions that seem to rage one day and curl up and die the next. I believe that I may show how we are related sometimes... I weep. It is a horror to me that some may notice our similarities.
If you wish to know more about her, ask her.

I get obsessed with things and drink tea too.
I tend to stay obsessed though.

My brother used to embarrass me a lot when we were younger.

On the plus side, he's grown up into a really nice person, so there's hope for your siste yet! He still won't drink tea though...
