I never used to see the need for it, but I have it now and am happy that I do. There have been times that I might have missed a call that was important to me. I think the people who abuse call waiting are probably the same people who have poor etiquette in other areas of their life.

Another area where I have changed my mind is cell phones. I always hate to hear people having conversations in grocery stores, etc. on their cells. Well a couple of weeks ago I received an important call from the facility where my mom is a resident and found myself answering my cell in Kohl's. I was so glad they were able to reach me. There I was talking on the phone in a store - one of my own pet peeves about other people. LOL! I did keep it short and talked in low tones but it pointed up to me that there are exceptions even to my own way of thinking now!
