Today I worked with a para who is used to doing "everything" and all the sub does is "assist." I found this to be making for a super long day and by the end of the day I had a major headache and couldn't take it. (It was in the plans that she leads and I provide assistance as needed.) We got along okay and she told me most subs "love" it when they have nothing to do. Are you that kind of sub? I like to be super busy and watching someone teach reminds me of my "observation" days in college. Would it have bothered you? I gently informed her that if I were to be back we would share the "load" and she said that would be great. God willing I have no intention of going back but at least she got my point.
