Driving Me Nuts

Okay well this guy I work with is really strange I mean he is totally crazy no really he is like yesterday I was out smoking on my lunch break and he comes over and is all like " are you trying to be like Daniel............You think your grown" well first of all it's my life and I will do what I please and second why does he keep thinking that he needs to look out for me seriously if I wanted that I wouldn't seek it from him any way I am sick of it and next time he "needs to talk to me" like my father I am just going to tell him to back off and I don't need his advice or what do you call it mentoring and that's that and I don't know why I let him get under my skin like that until then
