Boring Conversation.

Have you ever gotten into a conversation with someone where you have lost interest and they other person keeps dragging out the conversation. There are a few tricks that work, when you loose interest you can slowly direct your eyes past them or look to the right or left and act like something else has your interest. You can attempt to change the subject, give them a blank stair, or even start talking to someone that maybe passing by. They will catch on to these and feel like whatever they are saying doesn't matter, well at lest to you anyway. But be sure to not do this to often other wise people will start catching on and just think your strait up rude. Comment if you have any luck or any other ideas.
