Have u been tainted?

I was okay until I met a friend whom shall remain nameless (MAV). I was just as normal as any person you could wish to meet until this person (MAV) came into my life and then everything became confusing. Things that used to make sense no longer fit into the parameters of what we would call a "normal" existence. I would not divulge this person's name (MAV) out of fear that it would hurt his (MAV's) feelings but yes I have been tainted.
