I'd try to grab a moment with him, Melissa, and try to check things out. Sometimes, I know that I think I've been terribly inpolite and inappropriate with someone, but when I check things out, I realize that I've totally blown things out of proportion. Just take a moment to check your preception of things with the individual and get some closure. If you need to apologize, no big deal! We all get out of sorts and irritated in real life. It's about realizing that and making amends when we need to that matters! Good luck and I hope things work out.
