If I ever use that word I put quotation marks around it: "inappropriate". That's because there is no universal standard to what is "appropriate" or not. Different situations can be -- different.

It's the feeling you have that makes it uncomfortable to you. You may suspect someone of intentions that you don't like, and you may be right about the meaning of what they do. You may be wrong, too. Still you have the right to make your feelings your guide.

Well, that's what I think, anyway.
