There is a saying that I am sure you have heard: Treat others how you want to be treated. It makes a lot of sense. I have used this expression many times and have tried to use it to model how I deal with people.
I have always said that I consider spring to begin on March 1st. I do not wait until the 21st of the month. When the first day of March is here, so is the spring, as far as I am concerned.
