There is this guy at work who is older than me, and when I started working there we'd chit chat about this and that, like I do with other people at work. Around Christmas we were talking about something jokingly, and he said that he has something to give me. I made a joke about it, since I didn't think he was serious. Then he shows up with a really nice hand bag and a pair of earrings. I had a serious conversation with him, asking him why he did that. He said that he's noticed the way I work and I carry myself and he likes me a lot. I asked him "just to make sure, you do know I am married and I am unavailable, right? ". He said yes, he knows. I also asked him if he expects anything in return for his gifts. He said that he doesn't expect anything back and he did it because it came from his heart. After that, things kind of went back to normal; we acted like nothing happened. Then another day I find another gift in my locker. A couple days later- another. I know they are from him, but we never talked about it. I am flattered by his attention, but this is getting uncomfortable for me, as I think that the fact that he doesn't expect anything is really BS. What to do about it? What do you think his motives are, knowing that I am married and I never gave him signs that I am interested.
