You don't have to deal with them:-??

just be patient, with making know that it's not comfortable to be like that, and try to figure out their advantages and take benifits from them. It was a personal experience with friend who (almost time )only says Yes and No, at first i used to say: hey, im talking to u.. What did u say? Oh, i forgot, NOTHING!.. Hello.. Etc. Time after time she started to smile, come and sits beside me, but no words at all. Finally, i descovered something, she is very good listener, and gives very practical realist opinions when i need to, and above all she is a very good honest friend, so i took the benefits of her advantages, and we are friends 3 years ago. Believe me nobody believe that we are close friends, so give uhem the chance as i did and maybe u will find a surprise ^^

Correction: How do you deal with a non talkative person who answers you briefly? They do not talk and want you to run all of the conversation. It's boring. Sure it can be boring, but have you considered that this person may be very shy? As you are more extroverted,it is up to you to draw this person out. That is the mark of a good conversationalist. Ask a lot of specific questions such as, "What was the best thing that you saw on your trip? " rather than "So how was your trip?"

i agree with ayim. it seems like this person isn't really interested in talking with you so don't. but if you really have to talk to this person avoid yes/no questions. let him talk about himself or something you know he's interested in.

ignore 'em :P a friend of mine suggested duct tape LOL
