Looking for quick tips for a good guitar lesson.

I’m going to be giving a friend lessons soon and I really want to make sure I do the best I can in teaching so I figured I’d ask here for any tips for those who’ve been playing for a bit but haven’t taught all that much. I’ve been playing for 7 years now and was planning on loosely following the notebook that my lesson teacher wrote out for me years ago. She’ll be starting on my first guitar which is a strat. Just wanna make sure there isn’t something huge I should be doing that I’m not even thinking of rn since it’s been a few years since it took dedicated lessons.
