Forgotten words

When I was growing up, we used some words that no longer seem to be heard very often. The words we had used commonly have been replaced by what most of us elders consider as just plain vulgar. Some TV programs,are embarassing to listen too, especially if young children are around..
What ever happened to the use of words like: Golly, Gee Whiz, Holy Smokes, Gosh, Neat, Swell, Shucks, Oh Sugar.
 In our house, we never heard any curse word nor any expressions involving the Lord's name. We also could never refer to my mother as "she". My mother insisted on being referred to as "Mother". We loved, apprciated and respected our parents.
 I am appalled when I hear the way some grownups refer to their parents in hateful and grossly negative terms. I guess growing up in a loving family must have isolated me from such negative feelings.
