Coloring Easter eggs brings me great joy. I think I will continue to do this tradition the rest of my life , regardless of whether there are children around or not. 

This tradition dates back hundreds of years and most likely was first practiced as a right of passage for celebrating spring. At some point, it became a part of Christian celebrations of Easter. The shell is supposed to represent the tomb being sealed after Jesus was placed there. When it is cracked open in Easter Day, it represents the new life of Christ bursting forth from the tomb. 
Rituals and traditions exist to point us back towards important events in our lives and to remind us of why they are important. Coloring eggs at Easter is just one example of how rituals can be filled with joy and impact our lives significantly, bringing together the family and serving as a means of passing along our beliefs to our children and others.
