Easter Monday.
Just a regular work day. Not like in old country. Going wild with cups, cans, spray bottles with perfumed water or old fashioned buckets of well water, trying to spray every soul at least symbolically and soaking wet everybody but frail old people and very small children. For good luck. To honor ancient pagan tradition. To assure fertility in new growing season. But who cares what is the reason? It is so much fun!
