If you are like me eventually you will get bored with the what if's and the conversation will move on to something like this:
"Ok, so what if it does, what does that mean?"
"Well I suppose it means I'll have to handle it"
"Handle what exactly?"
"I don't know it hasn't happened yet"
"Well in that case lets not worry about it until it does happen"
"OK................, but what if it does?"
"Oh shut up!!"
