Remind that glosses are NOT translation of the English equivalent of words. They are only symbols of the ASL signs themselves, not translating the meanings. For examples, [gloss] is an empty gloss that no gloss can fit a sign. Another, the gloss MONO-TALK is a made-up gloss to identify the sign accompanied with a facial grammar.
Look at the ASL translation in the video, not the glosses, for full equivalent of meaning and concept.
