The further I go in my sign classes the more I find myself "thinking sign". This usually is a good indication of a grasp of the language. Just like learning French or Spanish. When you can think in the language and not have to mentally translate before saying what you want. I look at it as an accomplishment! My friends all know I'm taking classes and if I find myself signing I try to go ahead and speak what I'm signing as well. Thank goodness they are all supportive!
