You are not the first person who has been stumped by this!:hug:
Here is what you do. Pretend the needles are 2 separate straight needles, and ignore the cord that connects them. It's as if you had 2 pencils. When you knit, the points of the 2 needles are pointed towards each other in the center. Pretend one of the them is blue and the other is red. Let's say you cast on 20 sts onto the "blue" needle. You take the "red" needle and knit across the row. Now the sts are all on the "red" needle, and in your right hand. Now, take the "red" needle and switch to your left hand. BUT you have to turn it around so that the points of the 2 needles are pointing towards each other. Now, take the "blue" needle in your right hand and just knit the sts off of the "red" needle, just like you did before.
Don't worry about asking a lot of questions. No one was born knowing how to knit, and everyone hear is great about answering questions. People will walk you through every stitch if need be!
