Not at all, being a nice person is something that I'm very proud of and I love it when other people compliment my demeanor. You might have unknowingly used a tone in your voice that made it sound sarcastic, she may be hypersensitive, or the type to not be able to take a compliment (low self-esteem types to be like "Pff, yeah right." instead of "Thanks")
a lot of people think that being called nice is a pleasant way of saying 'you're not attractive'. I see a lot of posting from guys on this site about this subject as well. I suppose if you already are self conscious about the way you look, then you may take this compliment as an insult. so, if you are interested in this girl, or wish to make her feel better, I would compliment her appearance next time. I personally think that a compliment about my personality and/or intelligence is far better than one about my looks, but I've never been all that self conscious about that way I looked.
maybe its becasue she likes you and the last thing she wants you to think of her is a nice person.Being called a nice person mean you just want to be friends and that's why she took it to offense.Also maybe she views that you are lieing to her by calling her a nice person when in her own eyes she's not.
She was probably looking for something else, if you think about it 'nice' isn't really 'amazing' or 'kind' or 'lovely'. It's just nice. Like 'oh, that's nice'. I know this sounds really stupid, but it's how girls work. Any kind of compliment gets judged, like 'What does he mean by that?'. Crazy but true!
I'm pretty confused about what a guy means when he says a girl is nice, the reason I say this is because guys and girls probably tend to interpret the word in different manners. A guy I crushed on told my friend that I'm really nice, so that suggested to me that he was being freindly and probably didn't find me attractive.
I have to agree w Xenophobia. Nowadays, the word "nice" is a cop-out, a default response, a word you use to describe something you consider "blah", but don't want to be rude to that person. When a females describes me as "nice", to be honest I get slightly offended. Why? Because I think, "You couldn't use another term to describe me? Nice is so blah." I'd rather be called "sweet" than "nice" lol.
I think this girl thinks that, by you saying she's "nice", that she "doesn't strike your fancy", & therefore you're uninterested.
This is why I try to avoid using the word "nice". It's connotation is all screwed up nowadays, & leads to mis-communication. Tell this girl she's "cute", "sweet", "adorable" or "bubbly"...all are better than "nice".
