I don't think I've ever seen a sentence begin with "myself." I wonder why people have started using "myself" in so many strange ways. I guess maybe they think "I" is a bad word. I don't know for sure.

It's nice to know I'm not alone. Isn't it odd how some of the generation raised on the ridiculous self-esteem movement are afraid to use the word "I"?
