How do I respond to this email?

<p>I emailed a thank you note to my interviewer a couple days after our interview, and he responded saying good luck with your applications and with the whole college journey ahead of you. What should I say to that? I don't want to leave him hanging but I can't be like "you too" lol</p>

<p>It was their acknowledgement of your thank you, no need for a response.</p>

<p>I don’t think you need to reply at all. If you did, then he would need to thank you for your thank you to his thank you on into infinity.</p>
