How to respond to his "Good Morning" texts?

Anonymous
Someone I've been texting has gotten into the habit of sending "good morning" texts, and sometimes "goodnight." I simply don't always know how to respond to them. Replying with the same thing seems somewhat dismissive, yet replying with much more might imply things I don't intend.

It would be great to read some thoughts, experiences, or ideas you have. I'm mostly looking for thoughtful, clever, or otherwise interesting texts to send in response. Nothing too playful; I'm not up for flirting, and I don't quite know how I feel about things yet. I don't have any prior experience in these things.

Have you ever sent/received any particularly memorable messages along these lines? It'd be cool to see those, too.

Thanks!
