Your grandson, Theo, died last week at age 19 — a rare cardiac arrhythmia no one knew he had. You are 72. You are speaking at his funeral. Your son (Theo's father) asked you to speak. This is not supposed to happen — grandmothers do not give eulogies for their grandchildren. Write the eulogy you will deliver. The front row holds Theo's parents and his two younger sisters. 200-300 words. Just the eulogy itself, no preamble.
