Why might a guy on Instagram DM me privately to say he likes my picture instead of just clicking like on the picture?

Is it to start a conversation and it’d be too much to start a convo and click like? Or is he hiding something? I know you guys can’t answer for sure but you can take an educated guess based on your own actions and reasons or why you throng he may.
