Write one story-led English grammar video script for teen learners

Project brief

I need one English grammar point turned into a short video script for secondary-school learners. The topic, level and required learning points will be agreed before the work starts. Rather than opening with a rule and a list of examples, build a believable situation in which the grammar matters. Use dialogue or narration, then move naturally into a brief explanation and a clear takeaway. Include useful visual or action cues so the script can actually be filmed or animated. Keep it contemporary and age-appropriate, not childish or lecture-heavy. This is one paid script, not a whole series. Please send a relevant educational writing sample and tell me how you would approach the scenario.
