Hi -- these really aren't either/or words... they mean two different things. 1) Reflect - This can be a person (This really reflects my personality) or a thing (These clothes reflect my good taste). Think about a mirror, which reflects the person staring at it. 2) Respond - This can mean to answer, for example a question or a survey. (Can you respond to my father's question? Can you provide a response to our survey?) It can also be a response to a situation. (The fire department responds to emergencies. The hospital responded to a need for more doctors in the city.) These last two examples mean that someone took an action. Hope this helps.

After some reflection, I suggest you to change the date of the termination of the contract. Please respond politely, Mr. Smith. No need to be rude. Reflect about the question and respond wisely. I hope it helps!
