jjs, join the club :)
Just get your instructor to demonstrate a few more times, with you looking out as you would if you were on the controls. What you want here is to get the picture in your head of what the flare looks and feels like, then repetition will build the correct picture and feel as you get a few correct, then a few more, then a few more. You will get it sooner or later - if you are like me, it will be later! No matter though because along they way to being an expert at flaring, you will become very, very good at the other aspects as well. Enjoy the journey.
