He's a quiet guy but how much can I try to converse with him without bothering him?

Honestly we don't even talk a lot but he works with me and I just started saying hi whenever I saw him and then one time he said goodbye when I was leaving.

And then next time I said hi he actually said hi BACK and asked me how my day was which baffled me and my other coworker because bro didn't know he could talk that much.

And yeah we have small talks like that and while I kind want to talk to him more I'm concerned that I might just be bothering him so how am I supposed to know how much I should say? 😭
