There really is nothing wrong with some idle daydreaming when you are trying to come up with some great conversations starters for the event or function you are about to attend. We all have lost ourselves in our dreams at times, only to be brought out of them by the scalding hot water pouring over our hand or some other task we were involved in prior to getting lost in a dream.
What would it be to be able to walk up to a group of people and immediately know what to say and how to be comfortable? This is the case only if everyone in the group is someone you know and are familiar with, but not always the case. In fact, my job here is to try and prepare you for the party, function, or event you are about to attend so you can comfortably have a conversation with a certain lovely lady.
You are going to need to find different ways to get yourself lost in thought. This means this particular combination is worthless without the previous one, so allow the two to work together for you. Not unlike a cheesy flashback from a TV sitcom you can absolutely think and wonder what the situation you are going to find yourself in will present you with.
