Eggs are synonymous to Easter. The mere mention of Easter would bring to mind eggs, chocolate eggs in particular. Easter bunnies and eggs are surely the product of a commercial ploy, much like Christmas and Valentine's Day. I must admit that it won't be fun without them.
For the Christians, Easter has a deeper and more somber meaning. Eggs still play a part but it symbolizes rebirth or resurrection.
For foodies, Easter means feasting and eggs in many forms, among other things, are usually present.
