Aloha Doctor and Thank you! I'm attempting to help a friend. He and his mother, both, smack their lips while conversing, several times in a conversation. I'm with the impression that it could be that they are trying to think of the next thing to say, but as I've been searching online, it seems it could be "Tourette's Syndrome"... I'm not sure. Any ideas?
Mahalo, Thank you, o much, from Hawaii!
