Special Treatment

Is he your age? Or is he older? If he is your age maybe he does like you. I mean a lot of people have been known to try to win over they like with food or other treats. If he's older than you by a bit maybe you remind him of his daughter or niece or someone. Or maybe he's just the friendly sort who sees something in you that makes him want to be friends. If group mates are picking on you about it, ignore them. They're the ones with the problem not you. They're just jealous because he's bringing you a treat and not them.

Don't be prejudiced. What is wrong if he cares about you? Should you also care about him, for the sake of good relations and fruitful human beings. CMIIW

The key phrase is "I don't know how to react...." This tells me that there is improper communication between the two of you. The solution is communication. You may need to take him aside, let him know his actions are making you feel uncomfortable and ask him to modify his behavior. Better now than later, it will be worse if people get the wrong idea. If he doesn't respect your wishes, you may have to take it up with your supervisor. Be careful but do not let it go on too long. A soiled reputation is difficult to clean.

There's no doubt that he likes you. Are you even close friends? Do you feel comfortable with him? If you feel awkward with him then you should just tell him why he is acting this way.

thoughtful gesture... but if it's making you uncomfortable, i think you should just tell him exactly that.

Well, a few gestures here and there is fine with me. I would enjoy it with my team or friends; like when he comes up to give me some snacks I will share this with my team mates. But if it's already to the point that I am becoming uncomfortable, and of course affecting me at work, I will probably have a casual talk with him about this. I of course will make it sound as if I am just thanking him and I am not resenting it, but I will tell him that some people might take it the wrong way and I will be totally upset. I will still of course offer that we can still be friends, but put it in a more professional level. I can't just go and talk to him about how this makes me uncomfortable because the tables might be turned and I might end up being someone who reads a lot of things even to the most innocent of actions. Unless of course you know him well enough that this happening is very unlikely.

You wouldn't really know unless you ask his intentions isn't it? It is difficult to assume but his niceness signals that he likes you. If it bothers you too much just tell him nicely to stop.
