My bloke has some serious paranoia issues.

We were watching a programme and the main character said she thought one girl may have strangled or choked another. All I said to that was
"Women don't have the upper body strength to strangle someone"

It was a throw-away comment on my part and I thought no more about it until I realised he had gone very quiet. He looked at me strangely and said
"You've really thought about that haven't you? No, you have, haven't you? Done some serious thinking about it?"

To which I replied (please bear in mind that I wasn't really paying attention to the effect said comments were having on him)
"Well, they could but they'd need something like a rope or washing line...a pair of tights even".

Again, stunned silence. Then he muttered something about sleeping with one eye open from now on.
