My father always used to say "There's no panic like the realisation your head is stuck in something". I disagree.

Having a girlfriend has the amazing ability to create paranoia at the drop of a hat. For example:
"My tummy feels bloated..."
"I felt a bit sick this morning..."
"I'm late..."

All these are easily explained. A hearty meal has made her full and the same meal has made her feel ill the next morning. She was late for meeting me as the bus didn't turn up. I dunno, maybe it's just me, but I'm terrified of having kids. Anyone else like this?
