Is it normal to be wary of overly nice people?
Whenever people are overly nice for no apparent reason I get wary instead of being really nice back. For example, on my first day at a new job, I met this one coworker who was extremely nice to me. He was really open and told me about his life, what he has studied, how much he makes per month, where else he has worked and then he even gave me this drink (a fresh closed can of energy drink) without me approaching him or asking for any of these things. And from that day on, he has always said hi and how are you what's going on when he sees me. And when I didn't return his extreme level of interest and friendliness, he looked at me strange. With mean people, at least you know what you're dealing with, but with overly nice people it's like I should feel bad for not being overly nice back to him. :/
