I know that people here have talked me off this one before but it is still bugging me. Could I be exposed by living in close proximity to someone who lives in the UK during the mid to late 80's and made trips there in a bit during the 90's? I am really worried about having to share a bathroom. Am I over thinking this? It's my step dad and this paranoia bugs me cause he is really a great guy and has always been good to me.
