there is a guy at my job.I am not sure if he is just being nice or what. He always smile and say hi to me every time I passed by. We have each others facebook. and sometime, he would chat w/ me during work hour or after work. He would also ask me my lunch hour and have lunch with me sometimes. He seems like he is concerned about me. one time, my finger got paper cut and he seems worry about me or something. I am not used to guy being nice or concerned about me, so I do know if he is just being nice or actually interested in me.
