Have you ever gone out to a restaurant for dinner with a group of friends, only to find yourself completely uninterested with your company's conversation, their tired stories and trivial grievances?
Your eyes drift to nearby tables, hoping to find something else that better deserves your attention. You chew on the ice cubes in your drink, crunching out the chatter around you. You nod your head absentmindedly to agree with your companions whilst reflecting on the reality television shows you plan to watch when you get home -- "I wonder if Greg is gonna knock out that sucka Will for kissing his girl?"
When you're stuck in situations like this, don't you wish you could just pull out your Nintendo DS until someone brings out the food?
