What’s up with this guy I don’t understand his behaviour tbh?

He is very odd, like this morning he came up to me to have a small talk and saying ohh good job, I said did mean it from the bottom of your heart? He was like yea than it’s just little stuff he be commenting on, like later on the day I was working he calls me out loudly and says ohh Diana is finally working, than before that comment and commented good job again, not sure if he being genuine with me he did greet good morning to me early in the morning today and than when we was all supposed to leaving soon he comes by and says oh I thought she already left referring to me and just stuff like that why is he being like that?
