Baz Grg, You sure you said that to a lady? When she was saying, 'I love you'? May be you weren't paying attention to that lady or she must be butt ugly to make you come up with that. Well in my case, the bad thing I said to a girl was, a girl so beautiful had a dental surgery and came near to me with a bit bloated gum that kept her mouth open and she asked me how she looked. And I said to her that she looked like a cow. I don't know why the hell did I say that but she didn't speak to me for a week for that reason.
