I found pretty good playlist on YouTube about learning sign language for beginners. On the channel, Expertvillage, they have fifteen videos about this topic, and the signer, Melissa Schenk, teaches the viewers common phrases that people may need to say. In about half of the videos she gives a situation that people might come in contact with, and she teaches phrases that people would normally say but in sign from starting a conversation with a stranger, talking about the weather, and ordering food from a restaurant. I have watched the first two videos and having been only learning sign for a week and a half, it has been rather difficult for me just to remember how to sign these phrases. I have had to re-watch those videos multiple times just to get an understanding of the motion of the hands and trying to remember them.
