I have done my best to become a very positive person. It's hard to live with my husband and not have some of that rub off. :) He's the most positive person I've ever known!
Anyway, the next time you are dealing with someone difficult in your life, whether it be personal or professional - remember this quote I heard today. "Some people are put in your life as sandpaper. Avoiding them just keeps you rough around the edges." I think we all have people that are like sandpaper in our lives. And we love them anyway. :)
