Dear Overly Talkative Fellow Inuyasha Fan,
This may come as a shock, but the fact that we happen to like the same series does not mean that we are automatically Best Friends Forever. When you asked me if I was an Inuyasha fan and I said, "Uh huh," I did not mean, "Greetings, my beloved sister, whom I love dearly and would gladly die for despite only having met you thirty seconds ago. Please tell me your life story." I'm sure that you find detailed descriptions of your stamp collection and how and when you got your first period to be quite fascinating, but not everyone shares your opinion.
And just for the record, it's probably not a good idea to tell complete strangers your sexual fantasies. Particularly when said fantasies involve anime characters.
Your unwillingly captive audience
